Get markers in a TGraph2D

ROOT

Hi,

Is it possible to get access to individual markers (by point index) in a TGraph2D - say for example if you wanted to individually set colour or style per marker.

thanks!

No. you cannoot set the marker attribute individually.
You will be to make several TGraph2D and plot them on top of each other.

Hi,

ok thanks.

How about individually drawing TMarkers ? I know I can do this for a 2 dimensional plot, but how about in 3D? The TMarker only takes x and y coords, not z

thanks
Peter
