Here is another example, which works well:
Here’s a small method for toggling the legend via an API call, that can be hooked on to a button outside the chart. http://jsfiddle.net/highcharts/3Bh7b/76/
We do have a plugin for a draggable legend box, though it can’t be toggled on an off. See http://highcharts.uservoice.com/forums/55896-general/suggestions/912335-draggable-legend-box.
There’s a plugin for this, please see http://www.highcharts.com/plugin-registry/single/8/Adapt-Chart-To-Legend
