Why is plot continuosly redrawing?
Hi! We have noticed that we have a fair amount of CPU load and memory churn, even when the application is doing absolutely nothing and we are showing no data. It seems that it is continuously calling our handler for the FormatValueLabel event? The stack trace is this: DiagnosticAnalyzer.Module.Commo...

Detecting and ignoring zoom mouse clicks
Hi! When the user clicks the left mouse button inside our ViewXY graph, we want to handle that (e.g. by centering a Band around the click). We do this by handling MouseClick and it works fine. We would also like to preserve the zoom functionality. But when the user zooms using press-drag-release, we...

Using StaticResource warns "Chart objects parent changed"
We have several annotations and elements which use the same style. So we tried to specifiy these in a static resource, e.g. <UserControl.Resources> <lcusb:LineStyle Color="Black" Pattern="Dash" x:Key="CursorLineStyle"/> </UserControl.Resources> And use them like this: <...

Hiding "Units" in LegendBox3D
Hi!
It is not quite clear how we hide the text "Units" in the LegendBox3D? We can set the UnitsColor to have an alpha of 0, but it will still take up space?
Or can we customize it to something else than "Units"?

NRE when disposing chart with bound PointsLineSeries3D
Hi! We are using SemibindableCharting, version 7.2.6.4001. We have a 3D chart and drawing a PointLineSeries3D with PointsCompact bound to a SeriesPointCompact3D[] array. When we dispose the chart, we get the error below - it seems the wpf is setting PointsCompact to null and the chart doesn't like t...

Re: Correct implementation of FormatValueLabel?
I assume this would require us to rescale all the actual values?
That would be a bit impractical - the user might start with a plot from [-2;2] but then zoom in to see [-0.150 ; 0.150] - we need to show the labels as e.g. -150m, -100m, -50m, 0, 50m, 100m, 150m
So I don't think that would work?

Correct implementation of FormatValueLabel?
Hi! I need to implement a FormatValueLabel handler, since we need values displayed with SI suffixes for kilo, milli, giga etc - e.g. "23.451m" instead of "0,023451" or "2,3451E-2". However, I cannot figure out how many decimals to show? I tried to use FormatValueLabelEv...

Custom rendered annotation is not transparent in Light Gray
Hi! When running your sample: XY view - Others - Custom rendering using the dark theme, the annotation background is transparent. :D But if you switch to the LightGray theme, it as not transparent? :evil: This is both for 7.2.5 and 8..0.1 Unfortunately, we want to use the LightGray theme AND we want...

Re: Chart keeps resizing axis - hangs UI thread
Solved! Switching between rendering engine 9 and 11 didn't change anything. And the ChartError event is not raised. However, I finally noticed that we had set en event handlder on the xAxis.RangeChanged event. And the event handle would always put a new image in the CircleAnnotation.Fill.Bitmap. And...

Re: Chart keeps resizing axis - hangs UI thread
I will try to get a workable copy to you - I just have to get it cleared with the customer. We don't get any exceptions :-( I will try subscribing the ChartError and adjusting the devicetype. Mouse interaction is already disabled. I am a bit uncertain on how to use BeginUpdate/EndUpdate with MVVM an...

Chart keeps resizing axis - hangs UI thread
Hi! Using 7.2.5.1 on .net 4.6.2, windows 7, 64 bit. We are using an XY plot. For certain sizes, it gets stuck in a loop continuosly updating the axis. This also freezes the UI thread. I have attached a small video clip showing it. It only happens for some plot sizes - most of the time it works fine,...

Re: Binding errors when disposing chart
OK - setting the bound properties to null would unfortunately require a lot of code (and code maintenance), since we have many bindings.
So we will see if we can live with the warnings before we start doing this.

Binding errors when disposing chart
Hi! We are using the semibindable library v 7, but we are getting some errors in the log when disposing the chart. I have tried modifying the sampe ExamplePointLineSeriesXY to bind the title of the x axis to a viewmodel string. When the m_chart.Dispose() is called (when switching to a different wind...

Re: Overriding scaling decisions in YAxis Autofit
I'm afraid this is not exactly what i was looking for. Assume we have s graph that's more or less a straight line from 0,0 to 100,100. Now, the user zooms in on the xrange to see [5;30]. In this case, I want the YAxis to adjust to [0;50]. When he then zooms further into [8;12], I want the YAxis to a...

Overriding scaling decisions in YAxis Autofit
Hi! For some xy graphs, we would like handle scaling in a customized way: The Y minimum should be 0 and the Y maximum should always be rounded up to 10^n, 2*10^n or 5*10^n. So 0.01, 200 or 5, but not 15 or 3.5 - in this case the axis should go to 20 or 5 respectively. Now, we can do the computation ...
