[Answer]-Dc.js: Tooltip does not display

by

1👍

Tooltips are built-in to dc.js as .title properties on a chart object.
Try something like this on the chart object:

.title(function(d) {return d.key + 
    " £" + currFormat(d3.round(d.value)) + 
    " (" + d3.round((d.value / d3.sum(siteqtysum.all(),
     function(d){ return d.value;}))*100,1) +"%)";})

This will generated a tooltip against a row that says e.g. 'London £1234 37.3%'
You can add text "\n" in the title to get a linefeed in the tooltip.
