Execution result acquisition method

Hello.

I am trying to learn a Kalman filter using MATLAB.

Studying using the site of the following URL.

https://jp.mathworks.com/help/coder/ug/c-code-generation-for-a-kalman-filtering-algorithm.html?lang=en

I can create a graph, but I don't know how to get the plot data.

Please tell me how.

Thanks.
