The function plotxy() is not recognized

Hi all

I'm trying to plot two functions (throughput and delay) of the variable n against each other, i.e. throughput as y and delay as the x axis.

I have the following line of code:

tput_vs_delay = plotxy(tput, delay) 

But MatLab does not recognise the "plotxy" function:

% Unrecognized function of variable 'plotxy'

I found the function on the link below:

But I can't seem to use it in my code in R2019b.

You need simscape toolbox to use this function: https://www.mathworks.com/help/physmod/simscape/index.html. Also, you need to call it like this

simscape.logging.plotxy(x, y)

Note that x and y are not vectors. These are simulation data generated through Simulink.

Thanks for your prompt response Ameer - I will look into this.
