How to plot multiple data sets on the same graph

The following coding is only plotting the first two variables on the plot.

plot(years,run_rate,'r-s',years,CL,'g-',years,UCL,'g-',years,LCL,'g-');

Use hold on command between. For instance:

plot(years,run_rate,'r-s');hold on;plot(years,CL,'g-');hold on;plot(years,UCL,'g-');hold on;plot(years,LCL,'g-')

I tried that but it did not work. I think the problem lies in the fact that the variables CL,UCL and LCL are scalars and the variable years is a matrix. Do you know what should be done in the that case?

[Birdman]

Try the following for each scalar variables, but do not forget you need a vector instead of a matrix. So consider that you take the first column of years matrix, which is denoted as

years(:,1)

Try the following for scalars. The variables should have same length.

CL=CL*ones(length(years(:,1)),1)
UCL=UCL*ones(length(years(:,1)),1)
LCL=LCL*ones(length(years(:,1)),1)

This worked! Thank you!

[Birdman]

Can you accept the answer so that other people having the same problem will know there is a working solution.

[Aamna Sami]

Sure:) Thanks again for your prompt responses!
