Plotting graphs

Mary Looney — Thu, 18 Sep 2008 09:00:05 -0400

I have five graphs of data all plotted against the same x or time axis. The y axis is plotting throughput for 5 different parameters. I know how to plot each one individually. How do I plot all the data on one graph i.e. one time axis one throughput axis with 5 different graphs of throughput plotted? How is this achieved in MATLAB?

either:
plot first one
hold on
plot next one
etc.

or:
plot first one
line next one
etc.

or, and only, if all lines have same length, try something like

myLines = [line1; line2; line3];
plot(x, myLines);

maybe your peripheral code can gather this information directly in a matrix like 'myLines'.
