Hello, SciChart team!
i’m having some troubles with dated 3D charts.
so what do i need is to display samples which have 65k double points and a DateTime
Firstly i thought waterfall series would fill my needs, but i encountered these problems:
1. Charts wouln’t render Large series like 10 slices with 65k points per slice, 15k is ok (the charts just hang and don’t display anything for tens of minutes)
2. so the series would appear 10×15000, but i had issues with autorange and zooming when interval between slices is as small as 2 seconds (AutoRange is set to always)
my guess is that i need to set properties StepZ and StartZ correctly, but I couldn’t figure it out. i thought “StepZ” should be TimeSpan or smth like that, but it is DateTime too, so i tried some variations and didn’t succeed. could you please explain these properties’ use?
3. maybe this is feature but why do series go below 0 in the Y direction?

so then i reallized that i don’t always need to fill series with color and Waterfall series don’t quite fit ( even with transparent fill they have border lines on series start and end, and i thought i would add several PointLine RenderableSeries, one for each sample with fixed Z Datetime, but when i added such Renderable Series i get “SciChart3DSurface didn’t render, because an exception was thrown: Exception thrown: ‘System.IndexOutOfRangeException’ in SciChart.Charting3D.dll”
i played with example from latest SciChart version and attached altered solution to this post
so hit sidebar’s “Test” button and try both methods AddPointLineRenderSeries and AddWaterfallRenderSeries

Thanks in advance!
Best regards,
Alexander
