Can a uicontrol contain a plot?

G.A.M. — Mon, 20 Aug 2007 00:08:09 -0400

I would like to make a series of small plots where any
subplot, when clicked with the mouse, will open into a full
sized plot with extra details.

I have to do it all programmatically (in m files).

Can I display a plot in a uicontrol (a push button)?

If so, maybe I can add N uicontrols on a panel and display a
plot on each uicontrol and assign a function to
ButtonDownFcn that will grab some values from the plot's
UserData and generate a new full sized plot (with more details).

If this will work, can anyone give me some tips or examples
on how to implement it? It would be cool if there is a way
to add the uicontrols similar to the subplot method (i.e.,
by using m, n, p).
Thanks.

I'm definitely going to need some help with this. So far I
have learned:

"An object of class axes, can not be a child of class
uicontrol."

Any suggestions are appreciated.

A subplot can have a ButtonDownFcn

uicontrols cannot, as you have indicated you learned, have axes
as children.

However, there is a sense in which a uicontrol could
display a plot: pushbuttons and togglebuttons can have a CData
property,

    Truecolor image displayed on control. A three-dimensional matrix of
    RGB values that defines a truecolor image displayed on a control,
    which must be a push button or toggle button. Each value must be
    between 0.0 and 1.0.

So if you were to render the plot offscreen, then use the rendered
image as your CData, then the button would appear to have a
(static!) plot.

I am not recommending this method; it just would not be quite
right to say that uicontrols -cannot- have "plots".

Thanks for both the suggestions.

I think I'll try adding a ButtonDownFcn to a subplot. If
that doesn't fit my needs, I'll try the creative CData
suggestion. Thanks!

What is the best way to obtain the value of the current
subplot's UserData property (or any other property) from
within the function assigned to ButtonDownFcn? The current
subplot should be the one being clicked, right? Or is it a
bit more nebulous than that?

gca is the current subplot as you would expect.

get(gca,'userdata')

This thread is related to another one I started. Here is the
link:

http://www.mathworks.com/matlabcentral/newsreader/view_thread/154780

I cannot get the code:

get(gca,'userdata')

to work correctly yet.

Also, what is the best way to reference another thread in
this newsgroup? Is a link such as the one above OK?

Also, is there a faq that discusses things like whether I
should trim the previous messages or not when replying?

Thanks.
