How can I plot several lines on a figure with different colours when using plotyy?

x=eigen_h2(:,1);

y1=profile_h2(1:15000,3);

y2=eigen_h2(:,2);

y3=eigen_h2(:,3);

y4=eigen_h2(:,4);

figure

[hAx,hLine1,hLine2] = plotyy(x,y1,[x',x',x'],[y2',y3',y4']);

I'm trying to show y2' and y3' with different colours. I can show y1 with a different color, but y2,y3 and y4 all have the same color? How can I change their colours?

Thank you!

You should post an example we can use

What version of Matlab?

you should index the handle hLine2 (which is not a fortunate name choice as it is not the handle to the second line, but contains the handles to all the lines plotted on the secondary y-axes)

for ii = 1:4
  set(hLine2(ii),'Color',colorWanted(ii,:)) 
end

with colorWanted a 4x3 matrix with the desired RGB values
