fitting a custom curve in histogram

Hello,

I have a histogram plot data and I want to fit some curve that is "non-traditional". Instead of the usual normal, beta, etc plots, I want to fit it with something like log(c/x) where c is a constant. Any ideas on how to achieve this?

Thanks

One possibility:

bars = randi(20, 1, 5);     % Created ‘Histogram’ Data
bins = 1:5;

f = @(c,x) log(c./x);

B0 = rand;
B = nlinfit(bins, bars, f, B0);

figure(1)
bar(bins, bars)
hold on
plot(bins, f(B,bins), '-r', 'LineWidth',1.5)
hold off

You will have to experiment with it to get the result you want. I can only claim that the code I posted here runs!
