MATLAB: How to plot Simulink signal values saved to the MATLAB workspace on an axes

getting startedguiMATLABsimulink

I have to plot a signals in a MATLAB gui.
With Simulink I make a simulation and I save the signal in the workspace. I want to plot that signal in a gui axes but I dont know what I have to do.

I assume you run the Simulink model from the MATLAB GUI using the sim command. The data from your Scope will end up in the GUI (caller) workspace rather than the base workspace. So you should be able to plot it using something like:
plot(ScopeData.time, ScopeData.signals.values)
You may need to specify the handle of the axis on which to plot the data.
