Dear reader,

I am looking for a matlab code that can link the x-axis from figure1 with the y-axis from figure2. I need this functionality in order to simplify the visual inspection of 2 figures. Any help is highly appreciated.

For example, this code links the x-axis of both figures:

x=1:5;
figure;
plot(x);
a1 = gca;
figure;
p2 = plot(x+1);
a2 = gca;
linkaxes([a1 a2],'x');

Notice that now, as the user pans/zooms on figure1, there will be an immediate consequence on figure2. How can I modify this code such that it links x-axis from figure1 to y-axis of figure2?

Thank you,

You could create a callback and then add a listener. So a minimal example would be:

CallBack:

 function test(src, evt, ax)
  set(ax, 'Ylim', get(gca, 'Xlim'))
 end

Your figure:

x=1:5;
figure;
a1 = subplot(1,2,1);
plot(x);
a2 = subplot(1,2,2);
p2 = plot(x+1);
drawnow
xLimListener = addlistener( a1, 'XLim', 'PostSet', @(src,evt) test(src, evt, a2));

This example is on one figure. However, you can do the same with two figures.

Hi,

using linkaxes (or the more general linkprop) this will not work, because only the same property can be linked. What should work is to use a zoom object:

x=1:5;
figure;
plot(x);
a1 = gca;
figure;
p2 = plot(x+1);
a2 = gca;
h = zoom(1);
h.ActionPostCallback = @(hFig, hAx) set(a2, 'ylim', get(a1, 'xlim'));
