Is there a way to call a plot createFcn from another function in a GUI?

I have a GUI with an embedded plot. I generated a createFcn for this plot using GUIDE. Is there a way I can call this function from another function inside the same m file? This is what I tried and I get an error:

energyDiagram_CreateFcn(handles.energyDiagram, eventdata, handles);

Ideal solution will be to assign a handle to the figure in this CreateFcn that I can reference from outside. But I do not know the syntax for that.

Pavan - why do you want to do this? The _CreateFcn should be called automatically when you launch the GUI and so I don't think that you ever want to call it yourself for any reason. Please describe why you think that this is necessary.

Hello Geoff, Thank you for replying. I am trying to plot stuff on it based on the user input in the GUI. Once I have all the input I need, I am inserting the above code in a pushbutton to update the plot. Is there a much better way to do this?
