MATLAB: How to plot ScopeData from Simulink into GUI

Question

Simulating my model using

 evalin('base','sim(''Gen_Diff_Model_2'')')

to bring the variable ScopeData1 to the base workspace. However when plotting the data using:

    function Plot_Callback(hObject, eventdata, handles)
    axes(handles.HV_Measurement);
    plot(ScopeData1.time, ScopeData1.signals.values)

I receive: "Undefined function or variable 'ScopeData1'."

Thanks

Joe - since the ScopeData1 is in the base workspace, then you would need to use evalin from within your GUI to grab this data. For example,

 function Plot_Callback(hObject, eventdata, handles)
 axes(handles.HV_Measurement);
 timeData   = evalin('base','ScopeData1.time');
 signalData = evalin('base','ScopeData1.signals.values');
 plot(timeData, signalData);
