Thanks. I'll use this method. Because the X axis could be any valueset, it might be tricky to figure out the logical places to put custom tick marks, but that's my issue

Appreciate the help

greggorob64

Hello, I'm working on implementing the ability to view logarithmic X axes in my app. It works as expected mostly, except for one scenario: When you dont have a ton of data, the axis doesn't show much info. for instance, given the x values 177-8000, with 18 points, the log axis looks like this: https...

greggorob64

Been a while! I don't know how long this has been happening, but my chart is having the ChartError event fired every time I minimize my intensity grid window. My application puts my screen in an 'error mode' when an unknown error occurs, and this is causing a problem. Why is it an error state when t...

greggorob64

Your suggestion worked, thanks! You can see I chose the gray w\ black border to make it look like different charts (for better or worse). There is a 1px overrun on the right side that didn't use to be there, which is a bummer.

Thank you

greggorob64

Just quick question. Why you are not using ConstantLine as splitter. This is much simple object and automatically rendered between X min-max. The usage could be found in our Demo App example "Segments with splitters". All the best. I have no clue why I'm not using a constant line, I don't remember ...

greggorob64

I dug into the source (Sorry if im doing something bad by reposting this on here), but in AnnotationXY.cs:1191 is a call to fMax = (float)m_axisX.ValueToCoordNonDPId( , which returns the CORRECT xstart and xend. At around line 1238 there's a another method call to build the rectangle pnRenderLocatio...

greggorob64

In my app, I have a mode that stacks all of the axis as segments, as show in the first screenshot below. I am attempting to draw annotations as "Splitters" between each segment, to visually seperate each segment. After I upgraded from v7 to v8, the location is not getting set correctly. I'm using "V...

greggorob64

Sweet, thanks.

greggorob64

Thanks for the suggestions

greggorob64

Just got back from vacation, thanks for the update! This line drawing should work perfectly

greggorob64

I have a graph, with a legend, shown below. The legend has a units of "mm", which is the chart.yaxisprimary3d.units.text. However, my chart isn't keyed to change color based on y-value, its based off of the 'point' value, or intensity in my case. How can I still have my Y axis be mm, but have the lg...

greggorob64

Good morning:

I'm hoping to get rid of the checkbox on the legend. Is that possible?

Thanks.

greggorob64

We might go with the plane approach, I'm not quite sure. Will have to readress at a later time, thanks for the help.

greggorob64

Thanks for the help, solution works great! Thank you. legendSeries = new SurfaceMeshSeries3D(chart.View3D, Axis3DBinding.Primary, Axis3DBinding.Primary, Axis3DBinding.Primary); legendSeries.ColorSaturation = 100; legendSeries.WireframeType = SurfaceWireframeType3D.DotsPalettedByValue; legendSeries.C...

greggorob64

Hi, I have a point cloud, that i'm working on:

Is it possible to move the axis so they meet in like.... the center point? I basically want all of the axis to go through the 0, 0, 0 point.

Possible?

greggorob64

Hi, I'm doing some data visualization (image shown below), I have a point cloud, with some color coding based on an intensity value If you see in the legend, the legend color code is all dotted. How can I make it a pretty, colorful legend? Thanks! I dumped the code below too, there's not too much of...

greggorob64

Well I'm in a position where I don't know what the heck changed, but it magically started working. I'm using the following code to enable my logarithmic axis: axisX.ScaleType = ScaleType.Logarithmic; axisX.LogLabelsType = LogLabelsType.Regular; axisX.LogBase = 10; My issue is, when i zoom in, the X ...

greggorob64

I'll have to dig in and figure it out. There's only 1 chart and 1 axes in my application there. However, i'm very rigid in how i display the minimums and maximums and the allowable viewing area.

If I use setrange functions, is there a change that it will reset the scaling on the axis?

greggorob64

Still no luck. Here is pretty much all of the code that initializes an axis: var axisX = thisChart.ViewXY.XAxes[0]; axisX.Title.MouseInteraction = false; axisX.FormatValueLabel += XAxis_FormatValueLabel; axisX.ValueType = AxisValueType.Number; axisX.AutoFormatLabels = false; axisX.MouseInteraction =...

greggorob64

Real men don't read manuals...

they just bash thier head against the wall for hours and eventually just email you or pasi with outlandish unsubstantiated claims of bugs

greggorob64

I've seriously been using those charts for over two years now and I didn't know about control\shift + left click. The left clicking to zoom in about the cursor at that point might be sufficient for now. Thanks.
Thanks

greggorob64

Hello. I have a chart with multiple SampleDataSeries (shown below) I'm hoping to have the option to enable a logarithmic X axis. However, I can't seem to get the log axis to get enabled. It keeps looking normal. What am I missing? Thanks! Here's the code I'm using var xAxis = thisChart.ViewXY.XAxes[...

greggorob64

Hello! A feature my users love is the fact that you can: -Scroll-wheel to zoom X&Y -Control+Scroll-Wheel to zoom Y -Shift+Scroll-Wheel to zoom X Something that has been asked for a whole bunch of times is for similar effect when using the 'drag to zoom' rectangle. It would be amazing if you can hold...

greggorob64

I seriously can't figure out what changed. I moved some intialization code around and my performance penalities are gone. For right now, I'm getting good performance with 65k points. I havent scaled it up to over a million yet.

Thanks for the help.

greggorob64

I think for right now i'm just going to turn off 'point tracking' while im using FreeformPointLineSeries. My graphing package can toggle between linear axis (uses sampledataseries) and XY plotting (freeform point line series). When I come back to this issue, i'll probably use Series Event Markers to...

greggorob64

Hi. I have a chart with 3 freeform point line series (image below).

I have a LineSeriesCursor enabled as well, and the trackpoints do not track correctly at all. Am I missing something? The trackpoints are all over the place.

Thanks!

greggorob64

Something worth noting: I was running a performance profiler trying to find where my bottlenecks are, and I'm examining arctions handling of the 'moue move' event. In about 10-15 seconds of operation, I noticed that RenderingEngine11.IsMouseOverLine is getting hit 2 million times. Is there somethign...

greggorob64

The data is all X and Y points with valid data. No infinity or NaN.

This does give me some hope though. I just need to figure out where the bottleneck is.

greggorob64

hello, havent had to bug my arction friends in quite some time! I'm tasked with taking my data, normally represented in a SampleDataSeries, and we want to do an X vs Y plot. Makes the x axis 'not always increasing'. I tried an initial load of my data, and I got it to look how it's supposed to (image...

greggorob64

SnapToPoints=true doesn't help.
LineStyle.Width = 1 doesn't help

I'll work on an example and ship it your way.

Thanks.

greggorob64

Hello, its been almost two weeks since i bothered you guys! I have a chart with ~150 thousand points on it. I have a single axis visible, a single cursor, with 'tracking enabled'. I set the cursor value to be at the 'peak' of the plateau shown in the image. I have two images: one zoomed out, one zoo...

greggorob64

Hello. I'm displaying a sampledata series with 50k points, and all axis labelling totally default. I'm very happy with the performance\display stuff, unless you're really zoomed in. When i'm very zoomed in. I get a whole bunch of duplicate numbers. Is there a way for me to have this just display "1,...

greggorob64

Solution worked great, thanks. Only small hiccup i had was whether i had segements 'enabled' or not, to get the allowable width.

Now if I can just get someone to fix all of my automatic margin issues for me

greggorob64

To highjack this thread, you mention that performance is slower when using databreaking is enabled. Is this something I should be concerned about? I use it pretty extensively since the feature came in. If the performance is something concerned with, i'd rather go back to the 'invalid sample regions'...

greggorob64

In ViewXY I have the zoom settings as default (control is Y-only, Shift is X-only). When you press either of the keys, i'd like the cursor icon to update to reflect that. However, the cursor update doesn't update until you move the mouse. Is there any method or setting I can change to get the cursor...

greggorob64

That is perfect, thanks pasi

Hi, i'm using using graph segments in order to create what is effectively a stripchart (image below. you can see the ugly Y-axis labels that still need work!) I'd like some kind of visual seperator between the segments, even if its just like some kind of black (ideally nice looking) line. When you d...

greggorob64

Thanks pasi, i'll give this a try

greggorob64

These work and have been incorporated into my product, thank you!

greggorob64

Hello, this is more of an advice question than anything. I have a graph that is setup as segments, (screenshot on the bottom). As you can see, the Titles for the Y axis can get way longer than they should be, and it reduces redability. I'd liek to do one of three things: A) Insert newlines in the ti...

greggorob64

I tried checking out the rendered event, and it seems liek its getting triggered a LOT. Shoudl I have concerns regarding perfomance if I (possibly) move a bunch of annotations around?

greggorob64

I'm running into a tricky situation. When the user zooms in, I have to do a few things, namely: 1) Show\Scrollbars 2) Update chart margins (on account of scrollbar visibility) And then I also need to do something important: 1) move my annotations to the correct coordinates, based on the current x\y ...

greggorob64

This issue was fixed in 7.1.3.3

greggorob64

As always, thanks for the quick response. Works great!

(black trace is on top and width=2 now)

greggorob64

hello: I have 20+ axes (in overlaid mode). Each axes has a single sampledataseries, and all axes have 'axisvisible' set to false. It yields a graph that looks like this (shown below) Here's my goal, and i'm not sure how to accomplish it: based on the 'focused' row on in the top grid, i want to have ...

Switching to directx 9 makes the flickering go away. I'll start the arduous process of making an example for ya

greggorob64

I'm the last couple months i've a had a few recurring issues: 1) I am having traces completely dissapear from view and then come back when I move my mouse 2) I am having a lot of flickering in the cursors 'cross points'. I have attached a gif below, this is just showing the cursor flickering. You ca...

greggorob64

I tried 'no optimization' with the default shape (circles) and the performance was unfortunately not good enough to use. Will rectangles draw much faster than the circles?

greggorob64

Thanks pasi, the manual solution should work just fine. I have an 'enable stripchart' menupic that toggles the axis between stacked and segments, i'll have to also toggle the axis settings between 'auto' and the ones mentioned above.

greggorob64

I'm trying to find a way (in screen coordinates) to get the entire graphing area.

What i'm doing right now is innefficient: get all all yMin and yMax of all y axis, convert to screen coordinates, and find the lowest and highest values (and do the same for X axes).

Is there a better way?

greggorob64

I'm trying to develop a 'stripchart' (image below). I originally tried to use the 'stacked axis' layout to accomplish this goal, but ran into the following issue: The user needs to be able to easily add and remove axis from the screen. Since I dont want to physically remove the axes from the chart, ...

greggorob64

I'm running into a very similar issue, my solution was to use segements instead of stacked axes. Any series I want to show is assigned a segment. Any series I don't want to show has the Axis and Series' visible flags set to false and dumped into the last segment

greggorob64

So it sounds like with a few million points points, I want lots of pixels. When I used No optimization, the performance was bad (as expected).

Do you have any thoughts on how to increase the visibility somehow? I'm having a very hard time literally seeing the data

greggorob64

Whats the difference between pixels and lotofpixels? I'm not sure what the difference is and can't figure it out.

I plan on having up to a few million points.

greggorob64

I had actually set it to false first and then true again later. Something kind of funny is that i'm developing a graphing package for the engineers at my company, and I keep giving the users so many of the options that lightning chart has (its a giant wrapper around lightning charts basically). It e...

greggorob64

I can't set the resize by mouse to false because I need to resize the annotation by mouse.

The rotate by mouse is already set to false, the anchor still shows up sometimes.

But then I checked and I had this to true: annotation.AnchorAdjustByMouse = false;

Thanks for the help

greggorob64

Hi. I'm using an annotationXY, and i want the user to be able to move and resize the item, but not rotate. I want to completely hide the anchor icon, but can't figure out how. Any ideas? (anchor is on the left side of the annotation)

greggorob64

Thanks Nikalia, the mouse up event you mentioned works nicely.

greggorob64

I'm using LightningChartUltimateSource v.7.1.2.zip August 12 2016 258.38 MB Is this different that the 7.1.2.1 you mention? Also, here's the logic for my move events, they make sure that the annotation won't get too big or small. Its probably relevant to the issue i'm guessing. You might have to twe...

greggorob64

I'm using an annotationXY component, that I want the user to be able to resize and move (but not rotate). I'm running into issues where the handles are dissapearing a lot of the time, like this: https://i.imgur.com/75zpoIt.png Only two of the 8 handles are drawing. Its super inconsistant. Sometimes ...

greggorob64

That link worked. Thanks Pasi.

At that point it woudl just be easier to use a rectangle annoation with fill and a couple of line notations, which sounds like my only solution. It

greggorob64

Following up with my own post, I'm not sure how to approach using the stock points. They require Date/Time as thier X axis to connect to, and all of my Y axis are numeric. Is there way to make the two work on the same axis? Having to generate another X axis would be a pretty massive amount of work

greggorob64

Well I started with arrow-caliper annotations, and I'm not quite sure how to leverage that into what I need (something resembling candlestick). So far it just looks like an arrow with a line in the end, is there more to it than that I'm missing?

greggorob64

Hello. I have a chart, and would like to put a couple of candlestick 'points' at arbitrary coordinates. When you hover over a specific point, i want to add a few lines on the screen (easy), but also draw one of the candlestick objects away about 25px to the right. I put a little mockup below of what...

greggorob64

Hello! I'm working on adding some points with error bars, I have them styled and working the way I'd like, except for one issue, I can't capture a mouse over on the error bar! My goal is to have the same behavior as when I mouse over the series (I'd like to show one of my awesome tables, shown below...

greggorob64

You've foiled me yet again!

Out of curiosity, why are there two different properties for this? I just kind of assumed there'd only be one horizontal alignment property.

Also, you do have properties, literally thousands of them, can be hard to track down exactly what i'm lookin for.

greggorob64

You wasted like a day and a half of my work

. I took your example and generate an 'annotationstable' class, which will eventually be flexible to be used multiple contexts for my chart, but the table it generates looks great

greggorob64

Hello, got something new for monday morning. I have build a 'table tooltip' out of a ton of annotations, based on the lightning chart example, shown below https://i.imgur.com/djX7yPs.png Note the top annotation. It is a single annotation, set with the string: "Marker Text\n[cmd][otherstuff]" The cel...

greggorob64

Thanks, this should work great!

greggorob64

No I didn't, but this would work very good for my marker annotations I was using. I had to fight a huge battle to get the tab spacings to line up in the following image. A table would be pretty nice:

greggorob64

I'm running into an issue where I need to detect when the user clicks in 'negative' space. Is there a way to do this? By negative space, I just mean any space on the ViewXY that doesn't have a trace, annotation, etc. I have special mouseclick handlers for things mentioned above, which allows me to k...

greggorob64

To make it a *little* simpler, I just want each row to potentially be a different color. You could use your own markup language, with just the tag I need in there

...Now that I think of it, I might be able to do that myself without too much of a challenge in the LC source

greggorob64

I havent noticed any impact as of yet. However, I havent been doing any active scrolling or adding data that would make the labels update a lot.

greggorob64

I have an awesome graph using lightning charts, and i'd like to make it a little awesomer if possible (shown below) We've had multiple requests that the annotation below (used in other parts of the chart) have each row be color coded to match the color of the trace on the graph. The way I've had to ...

greggorob64

Hi: I have the following chart image (below). When you hover over a series, I add a marker point, with a nice title, to show information about where my mouse currently is. The title it uses lacks the customization to make it look relative to the annotations. I would love the ability to specify I wan...

greggorob64

Just thought I'd add that its fully incorporated into our product now and works great.

greggorob64

Two things: 1) I did a few experiments and did some zoomed in examining; and it's much choppier when using annotations VS seriesmarkertitles and chart titles. It really seems like its rendered much differently (and not as nicely) 2) The text looks WAY better when fontrender options is set to high. I...

greggorob64

That method is VERY hard to use, i've spent all day tinkering with it, and i feel like im farther away than i was frmo the very start.

greggorob64

I'm working towards enabling a clean implementation of allowing multiple Y axis. Something I really liek is the automatic Y axis placement, using as little hozontal space as possible.

I dug into the source code, and I pulled the 'set scrollbar colors' part of 'set theme' to its own public method (which set theme now calls), and was able to get it working.

greggorob64

That's definately the cause. The old way (with loading scrollbars immediately) 1) program starts 2) add scrollbars 3) apply theme the new way (lazy loading the scrollbars) 1) program starts 2) apply theme (some time passes) 3) add scrollbars I don't want to have to re-apply the theme to the entire c...

greggorob64

Hello. I originally added my scrollbars to my chart during the initialization of my chart. I'm doing all I can to improve startup time, so I modified my project to only create and add my scrollbar until the user needs them (they zoom in).

As a workaround, what would you recommend to use when one or more series are missing data? I can just zero the...

greggorob64

Howdy. I have a chart, shown below

Note the yellow giant rectangle on the left-hand side. After some digging, I figured out that those are float.NaN values. Is it possible to have those points not drawn at all, instead of the giant rectangle it shows as?

My version is from February (6.5.7 i'd guess). I'll update to v7 tomorrow and see if that helps.

I have a chart. The first time I load my chart, everything works correctly. When I load a second dataset into my chart, the axis values and grids aren't correct (a lot more than there needs to be).

I was hoping there wouldn't be a distinction...

greggorob64

Thanks Pasi, that was definately the solution. I couldn't figure out why the heck I held that series there either (at first). Then i figured out why! I made a seperate post about not liking the fact that my series event markers where showing underneath other series (link: http://forum.arction.com/vi...

greggorob64

Alright, i put together a sample. You should just be able to paste this into a program.cs and run All markers are getting display in reference to the first yaxis, as opposed to the axis that thier host series is a part of. In this example, hover your mouse over the red line, and then the blue line. ...

greggorob64

greggorob64

I'll go for the no-parameters option. I had originally just copypasted someone elses code snippet as my starting point.

As a side-note, the documentation for the antialiasing properties would have helped me a lot more if it indicated some default values.
Hope you don't mind the feedback

Thanks!

Hi. I'm working on getting an image exported from a lightning chart control into a devex report. In order to do that I have to have an 'Image' object.

greggorob64

Thats a tough compromise, i definitely would like it 'in between', but i guess the crosshairs bieng on top is the better of the two.

greggorob64

I have a follow up question for this topic.

Is there any way for me to make the series marker show on top of my cursors?

Thanks!

greggorob64

Thanks, this is great news!

greggorob64

Scratch that, I found the mistake.

If you subscribe to the FormatValueLabel event, the format settings don't do anything. I'll leave this up for posterity, or you can just delete this.

greggorob64

In order to spawn this dummy series, do I need to have samples in that dummy series? Memory usage of my graph is a paramount concern for me.

greggorob64

Thanks for finding my bug

.

Ive just started using the object initializer syntax and having quite gotten in down apparently.

greggorob64

I have some awesome SampleSeriesMarkers working on my chart, but I have a small issue, it is showing underneath other traces.

Is there a way to make all SampleSeriesMarkers show above all other traces?

greggorob64

As mentioned in my other thread, I'm using creating and adding a SeriesEventMarker on every mousemove event. This worked pretty flawlessly, until i change one specific property. As soon as I set Height\Width on the PoitnShapeStyle, the graph started uncontrollably flickering. In the screencap below,...

greggorob64

Using Arction has been a very positive experience for our customers. The zooming and panning functionality is great.

greggorob64

Thanks, I came to the conclusion that linewidth = 1 improved performance pretty quickly.

greggorob64

Thanks for the technical response.

When using a samplelineseries with (linesvisible=true, pointsvisible=false), does the optimization do anything? If so, what should i use for about 1M points? (all samplelineseries)

greggorob64

I'm trying to figure out what type of optimization I should be using for my sampleline series with several million points.

I don't know what the difference is between pixels and lotsofpixels. I'm not sure which one to use, and why?

Thanks!

greggorob64

I think using the different series type is definitely solution then. Right now, I'm reversing the array when the X range is descending (its much easier than modifying my code to work with the different series type).

I'll make the switch eventually.

Thanks for the info

Maybe using a difference series type is a better solution. We've been using SampleDataSeries up until now (which i believe has the best performance). The case where the X axis is reversed, maybe I can use a different series? Its not a big deal right now to manually reverse the buffer However, in the...

greggorob64

I was able to get the axis to show as reversed (my values go from RPM's 3700->900) However, my sample data is also ordered with data[0] is the data at X=3700, and data[100] is X=900. When i load the sample buffer in, the values are reversed because f the fact that the sample buffer always goes low x...

greggorob64

I'm having a very hard time getting my data to show up. I have my x axis set to go from 3700->900 (reversed!) and I have a single SampleDataSeries. My calculation for sampling frequency is series.SamplingFrequency = Math.Abs(1 / (this.XAxisDelta)); // Delta is -28 series.XAxisOffset = 900;// hardcod...

Thanks pasi!

I'm representing a line whose value will sometimes (but infrequently) dip below zero.

I'd like to highlight this line segment by turning the trace red for just that value. Is this possible to do? I'm not sure mechanism to use to accomplish this.

greggorob64

Thanks.

I'd like a 'mouse down' event when the user clicks within the graphing area of my View XY chart. How I accomplish this? There's no 'mousedown' for my XY view.

Thanks!

I need a vertical and horizontal scrollbar in my application. It would be great if I could use LC scrollbars for both. Instead, I have to modify LC's scrollbar to look like the standard windows one for consistency, and lose all ability to customize.

Thanks

greggorob64

Thanks. I didn't think that the scrollbar width could be affected by large/small change. I'll use the sample app you keep suggesting!

greggorob64

I have a bunch of SampleLineSeries, and I want to add a scrollbar to my window. So i add it alright, and am trying to update the scrollbar based on where my window is. So, in my Range Changed event, I do the following: scroll.Minimum = 0; scroll.Maximum = 16000; <-- sample maximum. I do have a delta...

I would like my SampelLineSeries chart to zoom in the following fashion: Wheel: Zoom in X Control+Wheel: Zoom In Y I've tried using thisChart.ViewXY.ZoomPanOptions.MouseWheelZooming = MouseWheelZooming.Horizontal; When I do this, and I hold the control key down, my icon changes to 'Y Zoom' as I'd li...

I don't know where my brain was at, for some reason i thought i had to set it to true. Anyways, I have it working, but I don't understand why. I have thisChart.ViewXY.AxisLayout.AutoAdjustMargins = false; thisChart.ViewXY.AxisLayout.YAxisTitleAutoPlacement = false; And I'm not specifying the locatio...

greggorob64

I am not using YAxisTitleAutoplacement or TitleAutoPlacement (tried setting them to true) It also seems like axisY.Title.DistanceToAxis = 50; (or any other number, is having no effect). also to no avail is axisY.Title.HorizontalAlign = YAxisTitleAlignmentHorizontal.Left; probably time for a sample p...

greggorob64

I have my margins hard set to specific values. However, I have my Y axis title placement set to automatic. The title is not bieng property placed, and is always over my Y axis. I know I can set 'distance to axis' but it would be nice if the autoplacement feature worked. Do i have any options? Thanks...

greggorob64

Thanks Pasi!

I have a need to the stacks in 'stacked y axis' to be configurable in height: 1) As you see below, we have both vertical and horizontal cross-sections. I really would like the horizontal cross-section to never take up more than ~15% of the overall chart. However, if there are only 2 stacked sonagram...

greggorob64

I figured out the issue, and it leads me to another question. My gridlines weren't showing because my X axis wasn't visible. A follow up question: I need to have gridlines without a visible axis. Is there some way to accomplish this? I know it doesn't make sense normally, but I have multiple charts ...

greggorob64

I'm totally wrong. When I downloaded source I (stupidly) opened the source sent to me in june, not the one from a week ago.

Oops! You can kill this thread.

I've been having issues trying to get my chart to disable panning when the chart is 'fully zoomed out' (i have internal values to what defines fully 'zoomed out'. The only way i could accomplish my task was using the 'before panning' event, and cancel is my chart ranges matched the fully 'zoomed out...

I'll give this a try; thanks

I have two charts on the same screen (image below), and the crosshairs always line up (i manually set them when the value changes). Is there a way to make them both highlight when i mouseover one of them? I got as far as adding MouseOver\MouseOff events, but i don't know how to programatically begin...

greggorob64

I'm trying to get the simplest possible gridlines (vertical and horizontal). For the X Axis, im just calling MajorGrid.Visible=true, and its working just fine. I cannot get the Y Axis to show gridlines (its overlayed Y-axes, with 1 visible at a time). I can get the minor to show up, but not major. W...

greggorob64

Thanks; I should be able to use this to accomplish what i'm working towards.

greggorob64

I have multiple Y Axis overlayed on a single X axis.

I'd like to rescale to have one of the axis automatically set the min\max to the lowest and highest sample in that axis.

Is this possible? ViewXY.FitView() does this to every axis, and I just want one.

Thanks!

greggorob64

Thanks!

greggorob64

Thanks for the reply. I'll have to do it manually. In this example, it starts at zero and increasing monotonically, but i'll have other examples that could have any [delta] and [offset]. I'll need to make a method to manually resolve an x coordinate.

greggorob64

I have a view XY chart, with 1 cursor (snap to points=true). My X axis values are increasing monotonically (0,1,2...). I'd like to be able to enter a value, "set my cursor to X = 50000". However, if the user enters 50000.123, i'd like it snap to [either nearest, or before/after] point. Can this be d...

I have a chart in ViewXY mode, with a single X axis and multiple overlaid Y axis. The X Axis units in the picture below is samples. They start at zero and increase by 1. I don't want the tick marks to get below the resolution of 1 unit. Showing .5 samples as a label is confusing our customer. Is the...

I have auto-adjust margins set to false.

It very much seems like there' a minimum chart area size relative to control width that's being forced on it. I'll try to take some time to generate a sample.

Going back to this; I'm thinking the root cause was me accidentally using Suspend/Resume Layout instead of Begin/End Update.

greggorob64

Ha, so i just noticed i was using begin\end update in some places, and suspend\resume layout in others.

Im mixing up my terminology. I'll try to make them all begin\end update and see if that helps

greggorob64

In the screenshots below, i set the left margin from 0 to 285. When the container is small, the margins aren't respected. When i make the container large before the margin change, it works just fine. When i resize the window (via mouse) from big->small, or small->big, it doesn't modify the margins o...

This issue is similar to my last one (index out-of-range exception) Forgive the humongous pic, i dont know of a better way to display the info. Im using Devexpress to display my lightning charts in a tile fashion. While maximizing and minimizing the chart a few times (makes the chart look like a thu...

That worked, thanks! I also had to make a small change, since the 'ownerview' got moved to read-only

Was I using it incorrectly there originally?

I took some time to readdress this, and i was able to make it much more manageable, albeit way more complicated. I'm initializing 15 (for example) lightning charts, each on their own tab. My order is now this: call 'new' on 15 usercontrols using async/await tasks to populate all of my data into the ...

I have a 3d spectogram pictured below. I don't want the Vertical Axis Data to dip undeath the bottom plane. Is there a way for me to accomplish this? I assume its an axis setting, but i'm not sure.

Thanks!

greggorob64

That would take a significant amount of time; but I probably should. It might be a few weeks; but i'll definitely want to readdress this and i can send you a zipped solution, thanks.

I am using begin and end update. I am generating a lot of graphs In a tab well. Some are standard 2d time domain, some 3d spectrogram, and some 2d However, all use begin and end update.

greggorob64

This method worked great. I added some padding to the farthest over label (by drawing "200 .") as the string.

Thanks!

greggorob64

Thanks, the upgrade did the trick! I can clean up a lot of the messing with Axis now that this is in place.

It might be worth noting that things like my axis positioning got pretty messed up, as well as my margins; its kind of a breaking change.

Im attempting to use multiple Y axis overlaid on top of each other. To get the graph to look reasonable, I know i'm going to have to do two things: 1) Add a position offset to each Y axis beyond the first in order to offset them 2) Change the location of the ViewXY so that the axis and graph area li...
