Hi I tried to create a legend in a histrogram plot. However the line in the legend has not the same color of line of the histogram. Here the part of the code for my plot auto RoHigh = ordered_up.Filter("Bcharge == 1").Histo1D({"","",26u, 2e6, 15e6},"roHigh"); auto RoHigh_neg = or…

Is RoHigh.GetPtr() valid? can you try using the name of the object instead? Do you have a small reproducer we can run?

Problems with TLegend Draw ROOT

Hi, does anybody have an idea why the legend seems to be printed wrongly? I got histo from root files and used DrawCopy() to draw them. The legend entries were added as leg->AddEntry(“histo name”, “some comment”, “l”). But I cannot see the correct correspondence with histos. Cheers [pic]
