Using 3 “y” axes for multiple plot
Hello,
I am working with multiple plots in MATLAB and I would like to use three different "y" axis for the different axes within a single figure. I have no problem using two "y" axes with yyaxis, I can’t include that function in my for loop (this loop reads the data from each column to be plotted from the Excel file). I read about a function called addaxis, but I don’t know how to use it.
Also, I would like the plots to have different colors for each "y" axis, since MATLAB defaults to red for Y1 and blue for Y2. Any ideas on how to achieve this?
Any suggestions would be greatly appreciated!
Best Regards!

This code is working but It can only plot 2 "y" axes; but if I try the addaxis in order to implement the third "y" axis, my code It´s not working:
