Error bars on TGraph

ROOT

Hi I have a TGraph made with data from a google sheet that I made. I have another set of data that is the standard error for all of the 10 points on the TGraph but I am not sure how to turn that data into actual error bars. How do you make error bars on TGraphs?

Read the Documentation; in particular, search for TGraphErrors.

Hi @Zach ,
indeed TGraphErrors seems to be what you are looking for. The primer to which @dastudillo linked has an example usage, the graphs tutorials have some more (e.g. the “gerrors” tutorials).

Hope this helps!
