Good day.

I wish to plot 6 different measurements sets in six different histograms with all axis set to the same unit scale, but not the same range. I am plotting from a TTree and the standard Draw() method works well except some of the x-axises have a -6 exponent, and others have a -3 exponent.

I would rather all had a -6 exponent so that the first graph could run from 20-25e-6, the next from 50-75e-6 the third from 100-120e-6 so on, not the third one being 0.1-0.12e-3 for example.

Does anyone know of a way to set the exponent on an axis?

Thank you.
