In short: create an extra plot handle for each marker type you want to show up in the legend, recording those handles. Use nan as the x and y coordinates when you do that. legend() passing those handles as the first argument.
legend() by default acts on the first plot handles it finds in the figure. In your case that happens to be the hex tiles. You need to tell more specifically which handles are to be legend()'d
