Create post-fit plots with post-fit results

[Tomoya-Iizawa]

Hi,

Is there any way to create post-fit distribution with using post-fit results from other distribution?
For example, obtainining fit results from the fit for mll distribution, and create pT distribution applying the fit results from the mll distribution?

Yes, this is one of the reasons why model_utils.match_fit_results was added. Create a workspace with the distributions you want to fit, perform the fit, obtain the fit results object. Then create a new workspace with the other distribution(s) for which you want to create the post-fit plots, use the model_utils.match_fit_results function to translate your existing fit results object to one suitable for that new model containing the new distributions, and use that translated fit results object to obtain post-fit plots for your new distributions. Please have a look at #431 for some more details.
