changing scale of x-axis in histfit

Hi!

I am generating some histograms with a normal distribution using histfit, and I need to change the scale in the x-axis. Specifically, I get 3 histograms for three different possible outcomes, and I need the scale on all of them to be the same in the x-axis.

Thanks!

More simply, I just want to choose the scale in the x-axis for a histogram generated using histfit

I am not certain what you’re doing, but I would consider using the hold function.

For example:

D1 = randn(1,100);                  % Create Data For Distributions
D2 = 2+1.5*randn(1,100);
D3 = 3+0.5*randn(1,100);

figure(1)                           % Plot All ‘histift’s On The Same Axes 
histfit(D1)
hold on
histfit(D2)
histfit(D3)
hold off
grid

Is this what you want to do?

not exactly, I want 3 separate histograms, and what I need to do is change the scale of the x-axis in each of them to make them the same. That is, I need a way to choose the scale in each case.

OK. I misunderstood. It’s just as easy though, all you need do is to set the 'XLim' property to be the same in each plot:

D1 = randn(1,100);                  % Create Data For Distributions
D2 = 2+1.5*randn(1,100);
D3 = 3+0.5*randn(1,100);

figure(1)                           % Plot All ‘histift’s On The Same Axes 
histfit(D1)
set(gca, 'XLim', [-4 8])
grid

figure(2)
histfit(D2)
set(gca, 'XLim', [-4 8])
grid

figure(3)
histfit(D3)
set(gca, 'XLim', [-4 8])
grid

Did I get it correct this time?

[María Jesús]

yes, thank you!!

My pleasure!
