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.
|
|
|

|
|
|
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.
