Color Intensity With Multigraphics

[mustapha_Ch]

hello everyone, I’m plotting numbers of graphics with the same colour, I want to change just the transparency of the colour, like the attached screen below.
how can I do It ?

Try with SetLineColorAlpha()

You need to use a GL canvas.

TColor → Color transparency

grep -r PreferGL ${ROOTSYS}/t[eu]*

I didn’t get, since i’m beginner could please give me an example

Transparency is not available with all graphics backends.
If you are running root on a Linux machine with X11 you will first need to
turn ROOT into GL mode with the command:

gStyle->SetCanvasPreferGL(true);
