Residual plot with TGraphErrors Object

[Edward_Finkelstein]

Hello,
I am trying to make a residual plot of point-fit/error, but I am using TGraphErrors object, so it doesn’t work the same way as with TH1F. Does somebody know how to do it?

I see that pad2 is empty. But you draw nothing in it … so that’s expected.
Your macro gives me the following plot:

So I made a separate file for histogram data to use for the residuals called dummy1.txt (since I see no other way to do it).
I still have some formatting issues.

1. The y-axis label on my runner plot is too high.
2. I want the runner plot to span the same width that my main plot does, but now it is not so.
3. I am not sure if the residual plot I made is really plotting data-fit/bin_error.

Maybe you can help?

You are double posting … one is enough …
