      1 /* Flot plugin for automatically redrawing plots as the placeholder resizes.

      6 It works by listening for changes on the placeholder div (through the jQuery
      7 resize event plugin) - if the size changes, it will redraw the plot.
      8 
      9 There are no options. If you need to disable the plugin for some plots, you
     10 can just fix the size of their placeholders.
