Add grouping in chart legend
Would be good to have grouping in legend so user can play with group as well as with legend item by clicking on it to show/hide items.
Click on group should work as click on each item in the group.
Could look like in this picture: http://forum.highcharts.com/resources/image/4056
+ in some cases groups could be series (in my example there could be series named Main Roads, local roads and private roads
+ Indenting group items would be a nice option for marking groups contents
Very interesting feature. It would be very nice to have a title to legend groups too.
For instance let's say 3 groups (Main Roads, Local roads, Private roads)
+-+- High speed roads
-+-+ Main roads
+-+- Secondary roads
-+-+ not paved
It would be nice to have the possibility to display each group in a column
