Hi Steema,

I've been using TeeChart for almost 20 years now.
Currently, I am using TeeChart Net for Winforms in Net Framework 4.8.

I would really appreciate if you could add a few more standard color PaletteStyles for the 3d plots than just the 5 ones.
http://steema.com/docs/teechart/net/lib ... Styles.htm

For example I would like to use an inverted Rainbow palette where red is for the largest value...
Also the maximum PaletteStep for the Rainbow palette is 25. Setting more steps just starts over with the lowest or highest color. The Palette should scale with steps like the others do.
The AddPalette function is similar to what I like to have but it does not automatically scale with Z values.

Also it would be great if the "UseColorRange" function would allow more than just 3 (start, mid and end) colors. Having an option for 4 ,5 or more colors in the range would add a lot of flexibility.

Additionally it would be great if the compute time for plotting large datasets could be improve.
I am regularly plotting 3d datasets of about 20,000 datapoints (150 X 150) and the chart update takes about 0.5-0.8sec which is really slow. On modern PCs with OpenGL rendering, that should be much faster.

Thanks
Holger
