Here's some code that plots two histograms in one figure and saves the figure:
% some random data:
f1 = 1.2+randn(1,100)/20;
f2 = 1.2+randn(1,100)/20;
% create the figure and histograms:
fig=figure;
hold on
h1=histogram(f1,'BinWidth',0.01);
xlim([1 1.4])
h2=histogram(f2,'BinWidth',0.01);
% save the figure:
saveas(fig,'histograms.fig')
You can see that the saved figure is accurate:
openfig('histograms.fig');
It's difficult to offer more specific advice because your code is a little confusing for the following reasons:
- The ind==2 branches will never be executed since they are inside the top-level if(ind==1) block - and ind doesn't change. And anyway, the second ind==2 branch will never be executed at all - it doesn't make sense to use the same condition more than once in an if/elseif construction.
- The code inside the first if(ind==1) and the second if(ind==1) create nearly identical figures, with the only difference being the second figure's plot has a title. I'm not sure what that's about
Be aware that each time you do
fig=figure;
a new figure is created, and the variable fig is the new figure. If you need to refer to a previously created figure after having created a new one, then you should store the two figures as different variable names (e.g., fig1 and fig2), and if you don't mean to create a new figure then remove the fig=figure; line, which will make the subsequent plotting commands plot into the current figure.
