plotyy two variables one with two series

Hi All, Please is it possible to use plotyy to plot two variables, temperature and speed, but for the speed coordinate I need to plot two series u and v. If it is possible, please how to do this.

Dear Abdulaziz, yes you can plot it. The following is an illustration of it:

temparature = 1:100;
u = rand(1, 100);
v = rand(1, 100);
plotyy(temparature, u, temparature, v), legend('u plot', 'v plot')

I hope it helps. Good luck!

If u and v have similar ranges, you can use plot(t, u, t, v) instead of plotyy(). plotyy() would be used if you have wildly different ranges for u and v, or if you wanted axes with tick marks on both sides of the plot.

Look at this example

t=0:0.1:10;
y=2*cos(t).^2
u=sin(t);  % speed 1
v=cos(t)   % speed 2
[ax,h1,h2]=plotyy(t,y,t,u)
line(t,v,'color',[1 1 0],'parent',ax(2));
