Hi Teemu,
Please follow the below workflow:
Include the following lines of code in the first file say plotting1.m
x = 0:0.01:20;
y1 = 200*exp(-0.05*x).*sin(x);
y2 = 0.8*exp(-0.5*x).*sin(10*x);
figure % new figure
plotyy(x,y1,x,y2)
Leave the figure open. Do not clear the above variables after you run plotting1.m.
Now include the following lines of code in a different file called plotting2.m
x = 0:0.01:20;
y1 = 500*exp(-0.75*x).*sin(x);
y2 = 09*exp(-0.75*x).*sin(10*x);
hold on
plotyy(x,y1,x,y2)
As shown above, on running the above script the curve is plotted on the same figure that was used in plotting1.m.
You can use this workflow to suit your use case.
