Question is simple. Given a chart with two or more lines, as in:

How to add an image to the legend, instead of a label?

plot(rand(2))
legend('image1','image2')

The above creates the legend with the text labels image1 and image2. Instead of writing something, I want to identify each curve with a different figure. Is it possible?

The easiest way I can think of is to make several subplot axes, including one containing the line plot

subplot(1,2,1); plot(1:5); 
ax=subplot(1,2,2);

Then you can manually drag and resize the empty axes and place them overtop the axes with the line plot. Then you can use the axes handles to fill the mini-axes with some image, e.g.,

imagesc(ax,imread('cameraman.tif')); axis(ax,'off')
