title: fix scale of multiple hist in MATLAB
body: <p>hi<br>
  I have a MATLAB program in which I draw several histograms. each time the hist is re-scaled (the axes). I want all of the hists to be shown at the same scale.<br>
  this is the program:   </p>
  
  <pre><code>clc  
  close all  
  PopSize=10^3;  
  SampleSize=1:100:PopSize;  
  NumberOfSamples=10^2;  
  Pop=randn(PopSize);  
  figure(NumberOfSamples+1);  
  hist(Pop);  
  sample=[];
  for j=1:100:PopSize  
  for i=1:1:NumberOfSamples  
      Pop=SHUFFLE(Pop);  
      sample(i)=mean(Pop(1:j));  
  end  
  figure(i+j);  
  hist(sample);  
  end
  </code></pre>
