Feature Request: Scroll bar for chart legends(dc.legend).

[rrameshkumar76]

It would be great to have ability to have a scroll bar for chart legends like in http://jsfiddle.net/ramseyfeng/80afu8kc/

We have pie charts with lots of slices and so lots of legends, It will be great to have a way within dc library for it to add a scroll bar. It works on the above example by wrapping the svg with a div and setting overflow: auto. I was not able to do the same as dc legend is in a "g" element. Is there a work around for this?

It's a good idea. SVG doesn't generally support scrollbars within the content, but I believe you can pan specific areas of the canvas using d3.zoom.

Another possibility is to have a miniature version of the legend which can be brushed or panned along, as suggested in #1259. (This is sort of a super-scrollbar.)

Or probably the easiest way to do this is to keep the legend separate (e.g. using html legends from #1329) and then just scroll using html, similar to the way @ialarmedalien implemented a scrolling row chart in this example: https://bl.ocks.org/ialarmedalien/0a4bf25ffc0fb96ae569a20f91957bc1
