Thread Subject: Link data to an "imshow"

I would like to do this

a=ones(100,100);
imshow(a);
%click the "link" button on the figure
%modify a
%the image is automatically updated because it is linked to a

Is this possible? Also, how do you programmatically link
plots with regular data (replacing the "click link" step in
the above example)?

Thanks,

Dave

It does not appear to be possible for images.

It also does not appear to be possible for line() objects
or patch() objects. It is, though, possible for lineseries
objects such as are created by plot().

newy = rand(1,17);
bar = plot(rand(1,17),newy);
set(bar,'YDataSource','newy');
newy = sind(0:pi:21);
refreshdata(bar,'caller');

It is allowed to use quoted expressions for the YDataSource, such as

set(bar,'YDataSource','newy(5,:)')
