Hello,

I’m trying to wrap the example from a previous discussion

Make each point different colors

Hello, I have a script which display graphs and I want to put a different color for each points. I know that with SetMarkerColor you can select the color for all points on the graph but I don’t know how can I put a different color for each points. Actually, my script display a canvas of 3 graphs and in each graph it is 3 points, I want to put 3 different colors for the 3 points on each graph. One other thing, I want to put a grid in those graphs, I put the punction SetGrid but it don’t worked.…

in pyroot but without success. These two lines are the issue,

    TExec *ex = new TExec("ex","DrawCol();");

    gr->GetListOfFunctions()->Add(ex);

Any advice, thanks,

Damir

@etejedor can you take a look please?

Hi Damir,

Can you elaborate a bit more on what you would like to do, exactly?

You have some code in C++ that you want to execute from Python?

[Damir_Devetak]

Yes; the same macro in the link provided but only in pyroot; The code will plot Graph points with different colors; I cannot map out this to pyroot. This passing of function TExec(“ex”,“DrawCol();”); doesn’t work,

Hi,
So you translated the C++ macro in the other post to a Python script, and you are trying to run that script?

Or what is it exactly that you are running in Python? Can you attach/copy it here?
