I use the plotyy for some work and need to change the fontsize of the lables so that it's readable in a document later. I know I can use plot browser and property editor to write the text, but i can't change the font size without changing the font size of the ticks. On the main axis I can simply click to label and change the size of the lable without affecting the size of the tick, can't seem to find how to do it with the second axis.
Thanks for help.

This seems to work without affecting the ticks or tick labels:
t = linspace(0, 2*pi);
y1 = sin(t);
y2 = cos(t);
figure(1)
[ax, p1, p2] = plotyy(t, y1, t, y2);
ylabel(ax(1), 'sin(t)')
ylabel(ax(2), 'cos(t)', 'FontSize',20)

[X|Y] labels inherit font size, name, etc., from the axes. To change the ylabel fontsize independently of the axes tick label sizes, save the axes handles and then the subsequent ylabel handle and modify its properties...
hAX=plotyy(.... % save the axes handles vector
hL2=ylabel(hAX(2),'Second Y');
set(hL2,'fontsize',16,'fontweight','bold','color','r') % example stuff set
You can, of course, use the named properties/values in the original call as well.
