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

gammahistogram

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?

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.

Oddly, it doesn't look like you can specify it at runtime. You'll have to save the handle, and apply LineStyle afterward.

h = histfit(data);
h(2).LineStyle = ':';

% Make up some data. (You should use your real data in place of x.)
x = lognrnd(1,0.3,10000,1);
% Fit the data
parmhat = lognfit(x);
% Plot comparison of the histogram of the data, and the fit
figure
hold on
% Empirical distribution
hist(x,0.1:0.1:10);
% Fitted distribution
xt = 0.1:0.1:10;
plot(xt,1000*lognpdf(xt,parmhat(1),parmhat(2)),'r')
