Plot two grafphs at the same figure

First of all: Merry Xmas and happy holidays to all!

Now here's my doubt: I want to plot two graphs at the same figure. But, each graph has it own program. Example: I have the program1 with the graph1 and the program2 with the graph2. Both graphs has the same x and y labels. I think that the solution may be using the savefig and the openfig commands but i didn't have sucess using both..

Thanks in advance!

You have to read about hold on

clc; clear all
x = linspace(-pi,pi);
y1 = sin(x);
y2 = cos(x);

plot(x,y1)
hold on
plot(x,y2)

xlabel('x-axes')
ylabel('y-axes')

I got that mate. But after i use the "hold on" how can i plot the second graph if it's from another file and i only have the .fig file from it?

Hold on works on .fig too. You read the data from the file and plot it.
