Hi,
I’ve been working on getting stacked mountain plots going on multiple stacked y axes. It all works well until I try and put a series on one axes and then a series with a different count on another axes. At that point I get this error:

SciChartSurface didn’t render, because an exception was thrown:
Message: Index was outside the bounds of the array.

Stack Trace: at xpj.tkj(IEnumerable`1 cka) at
xpj.DrawStackedSeries(IRenderContext2D renderContext) at
SciChart.Charting.Visuals.RenderableSeries.BaseRenderableSeries.SciChart.Charting.Visuals.IDrawable.OnDraw(IRenderContext2D
renderContext, IRenderPassData renderPassData) at
xlh.jsy(RenderPassInfo hc, IRenderContext2D hd, Int32 he) at
xlh.jsx(ISciChartSurface gz, RenderPassInfo ha, IRenderContext2D hb)
at xlh.RenderLoop(IRenderContext2D renderContext) at
SciChart.Charting.Visuals.SciChartSurface.DoDrawingLoop()

The 2 series have the same x range but different x values from each other. It doesn’t seem to happen for every set of values but I haven’t been able to work out what triggers it and have no access to the drawstackedseries code to see where the indexing is going off. This is happening on log axes but all y values are >0 and the ZeroLineY value is set to 0.1
