Hi all
I have a 4-column data and want to plot a 4d graph (3d + color). I am using tree and tree->Draw(“x:y:z:theta”,"",“COLZ”); but the color bar cannot be customized. Please help me if there is any other option or is it possible to edit the graph?

Thank you in advance.

Thank you for your reply. Please find the graph attached.

When I change the maximum and minimum the color bar cannot be updated and the output is attached.

I see. This TH3 is just created to draw the frame. When you draw a tree with 4 variables and option col the data are un-binned. A dot is drawn at each point. This setting has no effect.

Thank you so much for your help.

Could you please guide me what is the best way to plot a 4d graph that I can customize the bins and colorbar?

The simplest will be to put some limit on the 4th variable (the one mapped on the colors) when you draw the tree (2nd parameter).
