MATLAB: How to get X and Y values from a Scope Graph

scope plot excel

Hi everyone! I'm trying to obtain values of a scope plot to obtain two columns of X and the corrispondent Y value to plot a graph on Excel. Does anyone know how to do it?

Thank you in advance! I need it for my thesis

Click the second buttons on the "Scope" block to access the scope parameters. Click the "Data history" tab, check "Save data to workspace". Assume you use the default name "ScopeData", choose "Structure with time" for the format.

Once your simulation is done, go to MATLAB Command Window,

ScopeData.time will be the time vector and ScopeData.signals.values will be the signal values.

Use a To Workspace block to log your signal. Set its Save format to Structure with time and name it as ScopeData. Then, when the simulation is over, type the command:

 time=ScopeData.time;
 data=ScopeData.signals.values(:,1);
 plot(time,data)

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);
