Question

I want to plot two (or more) graphs in Matlab. I want them to be aligned one above the second one above the third and so on. However subplot is not the case for me. I also don’t want them both to be on the same graph in different colors, just to be one above the other. Is it possible? I’m searching for such a command but without any success.
Thanks in advance for hints!

If what you mean by “one above the other” is one “on top of another” then I think what You need to use is the axes command. Having said that, in order to have your plot be readable, I think more than two scales in the same plot makes it pretty hard to read.

This Matlab’s help page shows you how to do it, the gist of it is shown in the following script:

y2 = 1000.*rand(100,1);
x2 = 0:99;

% Plot the first data set
hl1 = line(x1,y1,'Color','r');
% Get the axes and configure it
ax1 = gca;
set(ax1,'XColor','r','YColor','r')

%Create the new axes
ax2 = axes('Position',get(ax1,'Position'),...
           'XAxisLocation','top',...
           'YAxisLocation','right',...
           'Color','none',...
           'XColor','k','YColor','k');
% Plot the second data set with the new axes
hl2 = line(x2,y2,'Color','k','Parent',ax2);

The above script creates the following plot with one set of axes in red and another in black.

Hope this helps.
