How to merge multiple graphs in a same plot?

Hi guys!

How can I merge multiple lines into one on the same plot? I have plotted the graphs, what command or tool i should use to combine them? Function for the plot: plot(r1x,r1y,r2x,r2y,r3x,r3y).

Many thanks!

It depends on how you want to combine them.

I would take the mean and std at each value of your independent variable (use the interp1 function to get values for all the data at the same independent variable values if necessary), and then plot the mean and 95% confidence intervals, using the t-distribution (the tinv function in the Statistics Toolbox) to calculate the confidence intervals.
