How can I change the color and font on the second y axis of a subplot?

I have a Matlab subplot:

subplot(4,2,2); plotyy(x,y,x,z)
xlabel('x','FontSize',8); set(gca,'FontSize',8); legend('y','z','Location','Best');
set(legend,'FontSize',8); title('y and z','FontSize',10);

But the font on the right axis is 10, not 8, and the color is blue. I would to change the color and font. Many thanks for any help!

Try this

close
x=0:0.1:10;
y=sin(x)
z=cos(x)
subplot(4,2,2);
[ax,h1,h2]=plotyy(x,y,x,z);
hl=legend('y','z','Location','Best');
set(hl,'FontSize',8)
title('y and z','FontSize',10)
xlabel('x','FontSize',8);
set(ax,'FontSize',10); 
set(h2,'color','g')

This is great Azzi, I have adapted your code, which also helped me make some additional changes. Many thanks!

Hello Azzi,

Is there a way to set ALL the Y axis colors in a subplot to black using the findall command?

I want to do this: set(findall(gcf, 'ALL Y Axis Colors', 'k'))

Can it be done.

Thank you

SSB, one way would be to use the plot tools. See icon in the lower right corner in the screen shot:

In the plot tools editor you can select the figure objects and change their properties. Once you are done adapting your figure you can choose > File > Generate Code... and learn how to do all those changes programmatically.

Thanks Mischa. Unfortunately, I can't figure out how to edit the right y axis of the subplot using the plot tools: when I click on it, I just get the left y axis properties for me to edit under the plot...

[Mischa Kim]

In the plot browser start by selecting the corresponding Axes (no title) and continue by changing properties as needed.

Thanks. For some reason I was just not able to click on the second y-axis, but I think I have it now.

You can also find the YAxis properties for left and right like so:

fh = figure;

x = 1:10;

y = 1:10;

%pltos on the left axis.

plot(x,y)

%plots on the right axis.

yyaxis right

plot(x,y*2)

%The YAxis object is stored under the Axes child of the figure.

%It has a property 'Color' that you can use to set the color to black.

%The line below will set the color to black.

fh.Children.YAxis(2) = 'k';
