How to make text in plot follow colormap?

Hi everyone,

I am trying to make a plot where instead of a legend I have used text to annotate just above each line. Here is an example:

I have used a colormap (winter) to color each line in my plot by:

set(0,'DefaultAxesColorOrder', winter(5));

I have then placed text at the chosen position by selecting an x and y coordinate.

t = text(12 ,1.4, NCA-OCY,'FontSize',16); %...ect

Q: How would I go about applying the same colormap to my plot labels?

Thanks!

Consider the crude example:

% you have some plots already
plot(-0.5:4.5,0.5:5.5)

cmap = winter(5); % use the colormap
for k = 1:5
    t(k) = text(0,k,sprintf('this is label #%d',k),'FontSize',16);
    t(k).Color = cmap(k,:); % just set the color
end

Note that t is an array of graphics handles instead of a scalar handle. If you were to need to change the text objects later, you'd still be able to.

This worked great. Thanks for your help!
