Plotting using s function

Is it possible to plot two signals as x vs y graph in simulink, using s function or is there any other way other than the graph tool?

[Birdman]

By graph tool, you mean XY Plot block in Simulink or something else? Is XY Plot acceptable or not for you?

[Brindha Chelliah]

Yes I meant the XY plot block. It was not plotting properly and it keep disappearing. So I felt that is not stable.

[Birdman]

Actually it is stable and works pretty well in my cases. How do you use it in your model?

[Brindha Chelliah]

Can I send you the model for verification? Your mail Id please

[Birdman]

You may share it from here, attach the model and send.

[Brindha Chelliah]

Attached is the file. I want to plot wind vs power

[Birdman]

Two questions:

-What do you mean by it keep disappearing?

-Is it normal for you that your simulations runs so slow?

[Brindha Chelliah]

The plot just disappears after sometime. No the simulations are not that slow.

Answer 1

After our discussion above, I am suggesting a different approach for xy plotting. It is much more efficient than it is in your model. I just save the data in structure format by using To Workspace block and by typing a single line of code in File->Model Properties->Callbacks->StopFcn, when the simulation is over, it automatically plots what you want. Just run the simulation and see the results. Hope this helps.
