Select axes for zoom in/out

I've got a figure with several axes. These axes are parented with a plot of several variables. Also, I've created a popup menu to select which of these axes I want to use. Until here all is OK.

However, when I select the axes and I push the zoom in button, The figure always takes the same axes.

Are you selecting the axes by using

axes(Handle)

If so then when you push the zoom in button you would be making active the axes where the zoom in button itself is.

When you select the axes handle through the popup, record the handle of the selected axes somewhere, and then when you go to do the plot, recall that handle and use it in the plot() call,

plot(AxesHandle, x, y...)

Hi Walter Roberson,

OK, if I understand you, well, you tell me that I should recall to plot() per each selection of popupmenu that I'm gonna do it.

Thanks, I will test it.

Hi Walter,

I tested it but I can't control which axis can zoom in/out.

for example:

ax(1)=axis(....);

ax(2)=axis(....);

hp=plot(ax(1),....);

In this example only I can zoom in ax(2) axis...

Hi,

Ok, sorry I hadn't seen it. Using, axes(handle), you can control the concret axis.

img = imread('cameraman.tif');
f = figure;
ax(1) = subplot(1,2,1);
imshow(img)
ax(2) = subplot(1,2,2);
imshow(im2bw(img,graythresh(img)));

axes(ax(1));

% OR PREFERABLY:

    set(f,'currentAxes',ax(1))

%Then:

    set(zoom(1.5))% will affect the first axes.

Also: Note that you can programmatically modify the x- y- limits of each axes. For instance:

set(ax(1),'xlim',[1 100],'ylim',[200 300])

AND: You might like to take EXPANDAXES for a test spin. :)
