MATLAB: Accessing value of toggle button in GUIDE

Question

I made a GUI in GUIDE, and ran into what seems like a simple issue, but I can't figure out what I'm overlooking.

I have an "execute" push button, which when pressed, checks the state of a "frequency plot" toggle button. If "frequency plot" button is active, a function to plot some data runs.

Inside the plotting function, I have:

if get(handles.toggle1,'Value')==1
fdata{1,1}=...
fdata{1,2}=...
end

I do this because the data can be used for different plots, and might not necessarily be used in this case. This is controlled by a toggle button. If the button is active, I add the data to a cell which is plotted.

I get the error: ??? Undefined variable "handles" or class "handles.toggle1".

I can't figure out why. I use this same line with set elsewhere in the program (not this function) and it access it fine.

Answer 1

Is handles being passed in to the plotting function?

Is the toggle button being created dynamically, or was it created statically and is part of your stored .fig file ?
