Highcharts - Keep tooltip showing on click
===

I have a highcharts graph, and I allowed the user to dynamically create their own Flags. Now I want to be able to click on the flag itself and be able to keep it's tooltip showing the whole time until I click on the flag again. The reason for this is to allow the user to give special meaning to points, and when they save the graph as an image, I want it to show the tooltip information they left on.

Anyone know how to do this or go about this? I can't figure out how to access the flags tooltip
