Hi all,

I'm using plotyy to make a graph of my data, but I cannot figure out how to programmatically edit the y-axis labels. Specifically, I would like to change the font size. Because I'm using plotyy, ylabel is off the table. Using set(ax,'FontSize',value) only affects the axis tick labels, x label, and legend.

Thanks,

Clay

在 MATLAB Online 中打开

 For example:
 x = 0:0.01:20;
 y1 = 200*exp(-0.05*x).*sin(x);
 y2 = 0.8*exp(-0.5*x).*sin(10*x);
 [AX,H1,H2] = plotyy(x,y1,x,y2,'plot');
 set(get(AX(1),'Ylabel'),'String','Slow Decay') ;
 set(get(AX(2),'Ylabel'),'String','Fast Decay');
 set(get(AX(2),'Ylabel'),'FontSize',30); % You can replace 30 with size you want.
 % Similarly for other axis.
