JQuery JQPlot - customizing the stacked bar

I have a unique requirement. 1. Present a stacked bar chart 2. The color of each stack can be set by the user in the db 3. The user can check/uncheck to add or remove a stack from the graph 4. The user can change the order of the stacks.

1开发者_如何学JAVA and 2 are fine, but I am stuck at 3 and 4. I am thinking I will have to create a custom renderer for the legends, so that I can add a checkbox to it, but after that what?

Anyone done this? Or have any pointers?

Once you created the renderer, you can bind some handler on the checkboxes' onclick event that would redraw the graph according to the user's choice.
