Thread Subject: how to plot a callout within a plot

hello,
i want to plot a callout (or zoom out) wiondow within a plot, so i can show a small part of the plot. (it just like we using the zoom out tool to see a plot, but instead, the zoom out is ploted within the plot, and we can still see the orignal plot).

how can i do that?
many thanks
nan

So, basically you want to have a figure with 2 axes in it.

Search the Matlab Help for 'multiple axes' and read the 'Using Multiple X- and Y-Axes':
http://www.mathworks.nl/access/helpdesk/help/techdoc/index.html?/access/helpdesk/help/techdoc/creating_plots/f1-11215.html

Second thing to do is to use the Position properties of the axes to place it in the right position (ah2 is the handle to your second axes):
set(ah2, 'Units', 'normalized', 'Position', [0.4 0.4 0.2 0.2])

plot(ah1, 1:10, 10:-1:1) % plot in normal axes
plot(ah2, 4:6, 6:-1:4) % plot in zoom axes

Check out 'magnify' from the FEX. I've never used it, but recall that it was a Pick-o'-the-Week a (long) while back:
