Error Histfit too many arguments

Hi I am trying to overlay a normal distribution and a gamma distribution in the same histogram. I am using the following code which give me a error message because I am using too many arguments under histfit. I tried to use the distribution fitter but my Y axis is density and I need frequency instead. Is there anyway to work around this?

Thanks in advance for your help

 number_of_bins = 10;
histfit(rain1positive, 10,'gamma','normal');
xlabel('mm');
title('station 1 jja');
umber_of_bins = 10;
histfit(rain1, 10,'gamma');
xlabel('mm');
title('station 1 jja');

histfit() has 1 required input and 2 more optional inputs. It does not have any name-value parameter options. The 3rd input specifies the distribution. Your 4th input, 'normal' is causing the problem. The distribution will be normal if the data produce a normal distribution so maybe I'm missing the point of this 'normal' input.

I'm trying to display both curves within the same histogram.

Hi

To display both curves in same histogram, try using below command after gamma distribution using "histfit":

hold on;

and then use “histfit” with normal distribution. This way you can display both the histograms in same figure.
