SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, and iOS Chart & Android Chart Components
We have annotations placed based on mouseposition. To snap the annotation to the position of the datapoints, we use
IDataSeries.FindClosestPoint(..) method to step to the nearest point, then applying it to the “X1”-property of the belonging annotation. This works well for most of the Series, but it fails for
InvalidCastException Specified cast is not valid.
Is this a known issue, any work-arounds for this ?
I would like to know if there is a possibility to export 3d charts to XPS format. I’ve tried using ExportToFile extension method:
sciChart.ExportToFile(filePath, ExportType.Xps, true);
While this method works well on 2d chart, it throws an exception:
at SciChart.Charting.Visuals.SciChartSurfaceBase.CreateCloneOfSurfaceInMemory(Size newSize)
at SciChart.Charting.Visuals.SciChartSurfaceBase.ExportToFileInternal(String fileName, ExportType exportType, Boolean useXamlRenderSurface, Nullable`1 size)
at SciChart.Charting.Visuals.SciChartSurfaceBase.ExportToFile(String fileName, ExportType exportType, Boolean useXamlRenderSurface)
It suggests there is no way to export 3d charts, am I correct?
