Simple question about plot

I want to increase the thickness of a line in a plot with the command 'Linewidth' followed by a number, for example:

plot(x,y,'Linewidth',3).

The problem is that I have a double-y plot , generated like this:

plotyy(x,y1,x,y2)

and I don't know how to do this. The commands

plotyy(x,y1,x,y2,'Linewidth',3)

and

plotyy(x,y1,'Linewidth',3,x,y2,'Linewidth',3)

don't work. Thank you.

Like Star Strider said, check the documentation

[AX,H1,H2] = plotyy(x,y1,x,y2,'plot');

set(H1,'LineWidth',1); %First graph

set(H2,'LineWidth',3); %Second graph
