So, if you head over to http://www.flotcharts.org/ and look at the grid in the demo at the top of the page, you will see that each column has an alternate color, much like alternate row colors in tables.I have searched all over, looked at the code for the site but for the life of me I cannot figure out how this is done. It seems to have something to do with the markings function but alas, I have had no success. Any one been able to get this working?
