help zooming while using ginput
Steve
on specific points and use their indices in the code. I'm using
[xvals,yvals]=ginput to get these points.
However, in some images, the region I want to focus on is small, and
using the zoom-in feature would be nice. Unfortunately, zooming seems
to be disabled when using ginput.
I am currently working around this by using a pause command after
displaying the image, then un-pausing (by hitting enter) before using
ginput, but this is kind of awkward, since I have to click on the
Matlab command window tab before hitting enter.
Is there a better way to zoom when using ginput?

You can't zoom by clicking on the figure when GINPUT is operating -- it
would be ambiguous whether MATLAB should zoom in or select the point when
you click. You could create buttons that call the ZOOM function with a
specific zoom factor, or you could try the first approach I found on the
MathWorks technical support site (www.mathworks.com/support) by searching
for "zoom" and "ginput":

or you could try this:

Alternately, if you're using GINPUT to get the coordinates just so you can
display them, take a look at the Data Cursor mode:

[All three of these came from the technical support site, from that one
search.]

First click is to specify the region you want to look at, after that resize with this value the axis and zoom in. with a second ginput you can now select the point you need.

I was wondering if you got the answer of this problem. I want to zoom in the graph, the get some points from my graph and again using the pan button i want to scroll the zoomed in graph to search for next point that i would like to select. Problem is when ginput is on i can't use pan button or can't touch the graph for any purpose other than selecting a point.
Thanks alot,
