MeshModel Get Triangle Based on X,Y Coordinate
I was looking at the 'Mesh models coloring, wireframe' demo and its mouse over annotation feature. I'd like to be able get the triangle based on X/Y values that sit inside one of the triangles that make up the mesh. Is this possible?

Re: Keep legend bound to inside chart
I would like to correct an error in my last post. When using the event to alter the legend box offset I can alter it using either the chart itself or the charts viewmodel ViewXY.LegendBox.Offset X & Y properties. When dragging the legend and the mouseup event happens with the cursor off the char...

Re: Keep legend bound to inside chart
This works if the user releases the mouse button with the mouse pointer in the chart. We are using binding for everything in the chart so in your example above I had to switch the changes to the legend box offset values to do these on the datacontext of the chart to get it to work. Unfortunately it ...

Keep legend bound to inside chart
Is there a way to restrict the legend position to prevent the user from dragging it outside the chart?

Irregular Shaped Surface Grid
I am inquiring as to whether it is possible to create a SurfaceGridSeries3D or something like it to create the surface of a racetrack. I have made a track using PointLineSeries3D but with 30 series items with 2000 points each it is slow to render and slow to update with user interactions(rotate the ...

Re: PointLineSeries3D Point Annotation Tooltip
Even something like in the 'Values tracking with markers' example would be fine but the SeriesEventMarker object appears to be for 2D only and searching the options that contain EventMarker does not seem to turn up any other event marker to use.

PointLineSeries3D Point Annotation Tooltip
As in the 'Surface Mouse Control' example with its mouse over annotation feature I am trying to replicate that for a PointLineSeries3D series object. I have done this with a 2D point line series. I am having problems with what I think should be a basic thing. I cannot get the MouseOverOn event to tr...

Hide Legend Series Item When PointLineSeries.Visible = False
When I toggle the Visible property of a PointLineSeries and redraw my chart it does what you expect but the item in the legend remains. Is there a way to hide/remove that?

SeriesEventMarkers - XValue wrong location
http://s4.postimg.org/b2ohw9o1p/Chart.jpg As you can see from the pic the Y position is correct but the X is not. I've looked at my code and checked that the SeriesEventMarker.XValue is being set to the correct value and that it is not being set somewhere else and have found nothing wrong. Have you...

Re: Series selection by mouse
Still getting the same result making the change you mentioned. Something really weird is going on. I was using the LightningChart.MouseUp event handler with the code above. When I tried to use the PointLineSeries3D.MouseClick event it never gets raised when I click on the series. For a sanity check ...

Re: Series selection by mouse
I am trying to more or less do the same thing using a PointLineSeries3D. I'm not sure what I am doing wrong but when I click on the line I always get : OverLine=false OverPoint=false index =-1 Point mouseScreen = e.GetPosition(_chart); int tolerance = 50; bool OverLine = false; bool OverPoint = fals...

Not sure what you are saying, the only FitView I know of is a function and I don't see a RangeChanged event in LightingChartUltimate.ViewXY.In FitView, axis.RangeChanged events

Re: LightningChartUltimate.ViewXY.YAxes.Fit(int MarginPixels
I've gotten things to behave by implementing my own custom Y margin code except for one case. When you leftclick and drag from right to left I have the ZoomAction set to 'FitView'. I have not been able to find an event for that to subscribe to. I guess if there is not one I can remove that functiona...

I have in my code in the routine to create a Lightning Chart : _chart.ViewXY.ZoomPanOptions.ViewFitYMarginPixels = 10; to add Y margin to my chart. This seems to only work when I left click and hold, and drag to the left to resize the chart to its aspect ratio of 1:1. So anything that causes the cha...

Re: Y Margins much larger than they should be
Thanks for the fast reply. Problem solved.
_chart.SizeChanged += SizeChangedEventHandler;
private void SizeChangedEventHandler(object sender, EventArgs e)
{
_chart.ViewXY.FitView();
_chart.SizeChanged -= SizeChangedEventHandler;
}
_chart.SizeChanged += SizeChangedEventHandler;
private void SizeChangedEventHandler(object sender, EventArgs e)
{
_chart.ViewXY.FitView();
_chart.SizeChanged -= SizeChangedEventHandler;

Y Margins much larger than they should be
I am hoping you might be able to help me figure out where I am going wrong. When my app initially opens the very first chart to be displayed always has way wider Y margin settings. I'm seeing something like 40 or 50 pixels where my setting is 10. This is with: _chart.ViewXY.ZoomPanOptions.ViewFitYMa...
