Subplots with equal "nice" y-axes -- is there a function?

Hello,

I thought I had seen a function somewhere that would modify subplots so that each of the plots would have the same scale (i.e., ylim) and all of them fit nicely. Kind of like "auto" for the subplot with the highest amplitude applied to all of the subplots.

Is there such a function, or option for an existing function?

Thanks

Once you've finished creating all the subplots (and you have the handles), you can set all of them at once by using :

set(AX_handles,'YLim',[A B])

Where AX_handles is a vector of axes handles, one for each subplot- for example:

for n=1:10
AX(n) = subplot(5,2,n)
end

A and B are your lower and upper limits. Finding the overall max will vary a bit depending on how your data is structed but it shouldn't be too hard.

allYLim = get(AxesHandle, {'YLim'});
allYLim = cat(2, allYLim{:});
set(AxesHandle, 'YLim', [min(allYLim), max(allYLim)]);

The curly braces around 'YLim' in the get command are needed, if AxesHandle is a scalar.

anyways, Jan, your solution works like a charm... as usual ;)

subplot(1,2,1);plot(t,x);
y1=ylim        %gets current limits

subplot(1,2,2);plot(t2,x2);
ylim(y1)       %sets limits to that of first subplot

what about "linkaxes" function?

Perfect

Worked perfectly for me too. I had to add it add the end of the script after all of the subplot calls.
