Re: Multiple SurfaceGridSeries3D and transparency

Transparency has serious limitations in 3D. It depends on the object order in the series collections and camera angle. You can use max 1 transparent or translucent series in the chart.

Hi Grandmaster Greg! LotsOfPixels uses single-colored texture. Pixels are either ON or OFF. Pixels instead retain correct alpha blending, so when having point color alpha < 255, multiple data points hitting same location will make it render in more strong color.

Hi!

You can achieve that best by placing SeriesEventMarker on each data point location. You can give individual color and shape for every marker, and you can have thousands of them in the chart. To hide the label of the marker, set marker.Label.Visible = False.

I hope this helps ;)
