How to share a variable between gui?

Hello.

I am having a problem trying to share a matrix between a table and a plot in GUI. This matrix is edited with the table and determines the offset of the graphs ploted. The code is below and I need to pass "plotset" between the three functions. Plot set is made in update_xrddata, and then eddited in a table in function data_table_CellEditCallback. After which its read in function update_Callback in order to plot data with required parameters. I have tried guidata, setappdata functions but could not get them to work. Any help is appreciated. Thank you.

function update_xrddata(handles)
   plotset=[plotname datasets offset];
 set(handles.data_table,'Data',plotset)

function update_Callback(hObject, eventdata, handles)
j=plotset(i,2);

function data_table_CellEditCallback(hObject, eventdata, handles)
plotset= get(handles.data_table, 'data')

How can this work? You don't have anything defined for datasets or offset. Show your setappdata() and getappdata() calls. That should work so you must have done something wrong with it.

Thanks that was more clear then the matlab website. Now to figure out how to clear the plot window.

cla() to clear the axes.

But the FAQ just tells you to use getappdata/setappdata which you said you had tried unsuccessfully. That's why I didn't recommend the FAQ to you and asked you to show your code.
