确定（识别）dc.js 图表类型

Question

I'm looking for some solution to determine or identify existing dc.js chart types on the page. I need it to work properly with d3.tip. For different types of charts I use different javascript code.

Answer 1

As answered by Matt Traynham on gitter, there is nothing built-in to do this, but you can add a member when you create a chart, as long as it has a name that doesn't clash with the chart members

var chart = dc.rowChart("#history");
chart.chartType = 'row';
chart.chartType; // "row"

PRs welcome!

Answer 2

chart.constructor.name

这对我有用。
