Hello, how to draw a TGraph in a “staircase” style? I mean something like this tinyurl.com/3c4k6xw See EAS-TOP data in panel (b): the two staircase lines describe the plus/minus error bounds. Each step corresponds to a “point”, but no marker is actually shown. How to make such a plot with Root? …

the staircase line makes sense only in case of binned data (ie histogram). Use a TH1 instead of a TGraph Rene
