CMAPLINE finds all lines in an axis and specifies their colors according to a colormap. Also accepts custom colormaps in the form of a n x 3 matrix.

EXAMPLE (generates screenshot)

%generate some data
x=(0:0.1:2*pi);
m=50; exdata=bsxfun(@plus,repmat(25.*sin(x),...
[m 1]),[1:m]');

figure
subplot(121);
plot(x,exdata,'o-','linewidth',2)
cmapline('colormap','jet');
set(gca,'color','k')
title('jet colormap')

subplot(122);
plot(x,exdata,'o-','linewidth',2)
custommap=flipud(hot);
cmapline('colormap',custommap,'filled')
set(gca,'color','k')
title('reverse hot colormap, filled markers')
