Hello, I am new to Matlab so please have patients. I have a m-file (created by others) as shown below. It calls a text file with 6 channels of data.
What I would like to do is create a new m-file (save-as) and plot for example the "Actuator_Extend_Pressure" as it currently is but add a second yaxis label from the "Analog1" channel which is: Ao1 = Motor Velocity Command (3000[RPM]/10[V]). The new/added y-axis would be in RPM and on the right side of the graph. So I would have a y-axis on the left in PSI and a y-axis on the right in RPM. I would do this for one or more files as needed and keep the others the same as they currently are.
Thank you for your help.
Current m-file:
