How to plot two different curves in one plot?

I am wondering how to plot two different curves with different matrix dimensions in one graph. At first i already did it, but the problem is when i was trying to set limits for two different y-axis. For first curve 0-10 and for second 0-90.

my currently code is:

figure
plot(fr792_10,k19);
hold on
plot(fr792_10vib2,j19vib2);
hold off

Any answer would be helpful.
