d3.js - dc.js piechart legend: display only top 5 -

-

i generating piechart (doughnut chart precise) has around 50 items, top 5 of them accounts 95% of chart. when display legend info, overlapping chart, since there many legend items. wondering if there option limit legend display top 5 items.

https://github.com/dc-js/dc.js/blob/master/web/docs/api-latest.md#legend

i not see option limit legend display top 5 or top 10.

you can modify dc.js library can following in legend mixin:

dc.legend = function () { ... //start modification var _maxitems; _legend.maxitems = function(maxitems) {     _maxitems = maxitems;     return _legend; }; //end modification ... _legend.render = function () {     _parent.svg().select('g.dc-legend').remove();     _g = _parent.svg().append('g')         .attr('class', 'dc-legend')         .attr('transform', 'translate(' + _x + ',' + _y + ')');     var legendables = _parent.legendables();      //start modification     if (_maxitems) {         legendables = legendables.slice(0, _maxitems);     }     //end modification ... }
