How to extend the fit in histfit? (red line doesn't continue past a certain point)

I'm trying to use a gamma fit, or at times a generalized-pareto distribution fit to my histogram data. However, the fit doesn't seem to extend as for as my data goes on the x-axis. Are there options within this histfit function call I should be using? Or do I need to do pd = fitdist(data, 'gamma'). And then use that pd object to fit a distribution with my original x range?

Post your data and code so people can work with it.

Unfortunately I cannot post the actual data set, but this is the command I ran: histfit(data, 10000, 'gamma') The 'data' is approximately 1 million data points. It is possible that is too many points for this to follow, or there is some implicit limit of the number of points it will show for the fit...?

See my answer (and ensuing comment) to effectively the same question here. Looking inside the histfit function, it seems that it plot the fit out to 3 sigma.

Thank you very much cyclist! I'll modify the file as I wish now.
