Plot a VS graph from simulink scope to Matlab

So, i build a dc motor. I want to plot a dc characteristic curve which are Torque Vs Speed, Torque Vs Armature Current and Speed Vs armatur current. How to plot this graph from simulink scope. I already connected to workspace but i stuck on how to proceed from matlab part. Its quite confusing.

Simulink Scope is always time based so the x-axis is always time. If you want Torque vs Speed, you need to use the "XY Graph" block. In MATLAB, you just run plot(Ws,T), assume the "Ws" and "T" saved in that "To Workspace" blcok are saved in array format and they have the same size.

thanks, this work jus fine

If you're working in R2019b or R2020a, you could use the XY visualization in the Simulation Data Inspector as well: Visualize Simulation Data on an XY Plot.

plot(ws,t)
