How to use subplot to keep the aspect ratios of the individual plots?

Hi all!

at the moment i have the following problem:

i use "plot" to get some nice plots of concentration-time profiles (x-axis: Time, y-axis: Concentration). Now i want to plot two x-y-plots side by side without loosing the look (ratio of x-axis to y-axis) of the original/individual plots? Can i do that with subplot? When i use subplot the first plot goes to subplot(1,2,1) and the second to subplot(1,2,2). The problem is, that the space for the x-axes is shrunken to half of the original size. So that the x-axes are much shorter than the y-axes.

Is it possible to plot the two x-y-plots side-by-side in a way that they look as if they were plotted "alone" using subplot?

I hope i could make my problem understandable :)

Thank you in advance! Darax

This function changes the aspect ratio of plots: http://se.mathworks.com/help/matlab/ref/pbaspect.html

There is even a specific example that looks exactly like what you are describing:

ax1 = subplot(2,1,1);
surf(peaks)

ax2 = subplot(2,1,2);
plot(peaks)
pbaspect(ax2,[2 1 1])

Thank you Daniel for your quick answer!

I found that example also... i tried i again... and yes this works now!

To not open another topic a quick question on the above example: when you change the aspect ratio of the first subplot like shown below,

ax1 = subplot(2,1,1); surf(peaks) pbaspect(ax1,[2 1 1])

ax2 = subplot(2,1,2); plot(peaks) pbaspect(ax2,[2 1 1])

what you get are two nice plots with the correct aspect ratios. But there is a lot of white space on the left and the right. I tried to cope with that using:

set(gca, 'LooseInset', [0,0,0,0]);

but that didn't work out. Do you have an idea how i can get rid of the white spaces?

Thank you very much again!
