Fit a histogram that has x-axis TDatime objects

ROOT
1

Hi,

I have some problems trying to make a fit of my histogram which has the x-axis of TDatime . If I want to make a fit of the histogram from the falling spectrum part, for instance with an exponential, how can I proceed? It seems like it is problematic to use a TDatime object as the x-axis input (which is probably rather reasonable), but I am not sure how I should do it in the right way

I attach a macro and the text-file which the macro reads, the macro should then be able to be run standalone. The fit-trial has been commented out.

Will greatly appreciate some hints along the way
Thanks a lot!

Hi,

since the question seems to be about ROOT usage, rather than python specifics, you’ll have better luck to get an answer on the ROOT support forum.

Cheers,
