Hi,

I understand that you are trying to draw a contour graph. Please refer to the below mention steps to create a contour graph.

Define range of Kp and Ki values in the form of a vector
Initialize arrays to store the performance metrics (rise time, settling time and overshoot)
Loop over all combinations of Kp and Ki values, simulate your system using ‘sim’ function and calculate the performance metrics for the system
Create the contour plot using the ‘contourf’ function for all performance metrics

For more information on contour graphs, refer to the following examples.
