I'm designing a GUI that calculate PID parameters, this GUI passes the Kp, Ki, Kd parameters to PID Controller on simulink and then simulate it. I'd like to display the scope of simulation (scope block) in a GUI window. How could I do it?
Log your data coming in the simulink scope to base workspace and plot the data in your gui after simulation.
To enable the scope data logging double click on scope, go to "Scope parameters --> History" and select "Save data to workspace". Structure with time is the best suitable format for data logging.
Now after simulation, scope data will be save in the base workspace.
To plot the data
I've made a similar script for optimising parameters in a Simulink model. If one uses the sim(model) in the GUI's script, by default this returns some variable yout of simulation results, the first row being timestep - as you probably know.
Then one could use setappdata and getappdata to transfer the data between callbacks.
You'll need a Axes window in the GUI (easiest to do in GUIDE). In r2007b to get the data to plot I needed to add variables to the GUI handle. For me
handles.variabletoplot = variabletoplot
seemed to work but I'll admit my understanding is fuzzy on this. You can use
to set the 'current' GUI axes handle for any succeeding plot commands, such as :
