Simple TF1 drawing problem


it seems that I have a quite simple problem that I am not able to solve. I have a TF1 function that has a (physical) allowed range of 10 to 150. Now, I want to draw it with an axis range of 0 to 140 to be able to compare better to a different plot. I tried various combinations of function ranges, SetRangeUser and SetLimits, but nothing gives the desired result. I attach the script and the plot is produces. Should be fairly easy to do, shouldn’t it? For the y-axis it is no problem at all.

Thanks for your help!
