LightningChart Support Forums

I have a question about the LightningChart.CopyToClipboardAsEmf() function. It seems that sometimes the complete graphs are missing if they have too many points* if you choose to use that function with the export format EMF. The same view area can be exported to other formats (PNG, JPG, BMP) without...

Since much time has passed in the meantime, I reopen this question: Is a LegendBox somehow configurable (especially scrollable)?

In the meantime I have found a solution. It was my error, not an error in LightningChart. Thanks to the support team for the direct help.

Hi, I have the following problem: My application has multiple charts on multiple tabs, therefore it has only one active tab at a time (the one that you can see). I want to change the color of a series in the active chart *and* to change it in the other tabs/charts too if it is present. My code works...

I thought about it again. The best would be a function like in windows file explorer: holding the right mouse button down on a file allows dragging the file, releasing the button opens the context menu. Transferred to LightningChart: holding the right mouse button down allows dragging, releasing the...

Right-clicking (and keeping the right mouse button pressed) on a chart area allows me to drag the chart (surely a LightningChart functionality). When I add a WinForms ContextMenuStrip (plus several ToolStripMenuItems etc. as children) plus an event handler function, a right click opens that context ...

What is the preferred way to temporarily hide a point from a PointLineSeries? Setting the points color to transparent does not really work as the point is invisible but still gets considered for the graph generation. Removing the point from the series seems to be the only way, but I also want to be ...

And what exactly is chart.ViewXY.GetGraphSegmentInfo().GraphHeight in a segmented axis layout? What does the value represent and what unit is it in?

Hi, I have the following problem with segment heights: I have a layout of three segments (A, B, C) with their heights being 0.05, 1, 1. All of the heights are of course relative values, not fixed ones. What I want is to assign a fixed minimum value (preferably in pixels) to segment A. I assume that ...

Hi Lasse, the second approach works very well (except that it is IsMouseOver() instead of IsPositionOver()), thanks very much! I didn't test the first approach.

Best regards

Hi, I have a chart with several annotations (among other stuff), and I want to catch the events of right-clicking on the chart and right-clicking on an annotation. Each right-click should be handled by its own event handler function. This works for the right-click on the chart, but does not work for...

Is it possible to assign an individual Z order to LineSeriesCursors, so that they run behind one graph but above another? I could only find the "behind" property that positions the LineSeriesCursor at the very front or at the very back.
