Using jquery and ajax to update an asp.net chart with new data

Using jquery and ajax to update an asp.net chart with new data

For starters I am just learning to use ajax so I apologize if this is a trivial question but I can't seem to find a good answer during my googling. I have an .aspx page which has a checkboxlist. As an item is checked, a new series is drawn on the chart, if it's unchecked then it gets removed. Im doing this all in the code behind now using mysql database calls to add and remove the series data. Is there a way to do this via jquery using ajax? Charts are returned as images, can an image be returned from ajax call?
