Hi, I have a problem automatically resizing axis in a plot. I first have a figure with multiple plots with the x-axis in the range [0, 1000] and I save that figure, then I want to save the same figure but with the x-axis in the range [0, 200]. I would like the y-axis to adapt to the new cut, so that the y range will reduce, in order to have the minimum values to contain the plots in the new x cut.
I tryied to resize using "axis([0, 200, -inf, inf])", but the y-axis doesn't readapt, and mantain the same range that it previously had. I would like not to manually search the maximum and minimum for every function because it would be time expensive.
I want to do that in a script and not manually because it has to be automatic. Thank you!

Try something like this instead:
aH = axes;
plot(aH,rand(100,1));
aH.XLim = [50, 65];
The Y axis should resize automatically.

If you have your data for x = 1, 2, 3, 4, ..., you can introduce a new variable
idx = 1:1000; % or idx = 1:200
and use in your subplots
plot(x(idx), y(idx)
