Hi , looking to create a plot similar to the plot attached. I have two sets of data which are similar and I want to compare them 'back-to-back'. How do I go about doing that on Matlab? I'm familiar with matlab plotting but with only very basic knowledge. Any help would be appreciated.
This is the image.
Thanks

I found that the easiest way doing it is to multiply the matrix containing your figure by .*(-1), and plot it as usual. It worked for me.

Wouldn't it be the most direct and easiest way to draw the data in one axes?
t = 1:10;
data1 = rand(1, 10);
data2 = rand(1, 10);
plot(t, data1, 'r');
hold on
plot(t, data2, 'b');

JL's "Answer" moved here since it's not an actual official "Answer" to his original question:
No it must be mirrored below y axis like in the photo. The intensities will be roughly the same but not quite so drawing the data in one axis won't show the difference well enough.

You mean like
plot(t, data1, 'r', t, -data2, 'b')
?
