Help me to plot a graph

x=[0:100:500];

y=3000+x.*250;

y1=y.*400;

How to plot both (x,y) and (x,y1) on one graph with suitable y axis ranges

Answer 1

Maybe like this?

x = linspace(0, 100, 501);
y = 3000 + x*250;
yyaxis left
plot(x, y)
ylim([0 4e4])
yyaxis right
plot(x, 400*y)
ylim([0 14e6])

Thanks Sam for the answer. However, yyaxis left & yyaxis right commands don't seem to work in Simulink block. Any suggestions? Rgds!

Hi @Ajay Ahuja

As far as I know, this left/right y-axis feature is currently not supported in the Simulink Scope.

If you really want to view two signals in one Scope, consider specifying the number of input ports on a Scope block.

For inserting a figure in a technical report, it is recommended that you send the data to Workspace and plot them out using yyaxis in MATLAB.
