plotting in gui

Hi All,

I am trying to desing a gui interface to interactively render plots. So I have a 2x3 figure pallet. All six have the tags axes_row11,axes_row12 ...and so on. I am trying to access these axes objects (from within a callback) by the following commands:

*********************************

mydata = guihandles(hObject);
axes(mydata.axes_row11);plot(1,1)
axes(mydata.axes_row12);plot(1,2);

OR

plot(mydata.axes_row11,1,1);
plot(mydata.axes_row12,1,2);

***************************************

Question: During the 2nd call to the 'Callback' I found that both axes_row11 and axes_row12 had been deleted and cannot be accessed anymore. Initating the commands 'plot'/'axes' is somehow modifying mydata by deleting certain handles. how do i solve this problem ?

please help

thanks,

rishabh

thanks you all for the suggestions. However, none worked. In the end I figured that somehow the tag field was being erased by invoking the 'plot'. So I simply did the following:

************** plot(handles.axes_row11,1,1); set(handles.axes_row11,'Tag','axes_row11') ************************* so that next time I invoked the callback, the tag was still there. thanks again

I use

set(gcf,'CurrentAxes',handles.YourTagHere);
plot(x,y);

To switch between axes in the GUIs I make.

giving the same problem:

**************************************

set(gcf,'CurrentAxes',mydata.axes_row23);

plot(1,1);

set(gcf,'CurrentAxes',mydata.axes_row13);

plot(2,2);

Have you tried using axes?

axes(mydata.axes_row11);
plot(1,1);
axes(mydata.axes_row12);
plot(1,2);

Hope it helps ;-)

If you are using GUIDE just do

plot(handles.axes_row11,1,1);
plot(handles.axes_row12,1,2);
