javascript - 如何在单元格单击时单击融合图表热图的事件？

问题描述

我对融合热图上的点击事件有疑问：

我需要一个点击事件来获取单元格点击上的融合图表热图，例如 http://jsfiddle.net/robschmuecker/3UWaA/3/ 这是代码。 

FusionCharts.ready(function() {
  var salesHMChart = new FusionCharts({
    type: 'heatmap',
    renderAt: 'chart-container',
    dataFormat: 'json',
    dataSource: {
      "chart": {
        "caption": "Top Smartphone Ratings",
        "xAxisName": "Features",
        "yAxisName": "Model",
        "theme": "fusion"
      },
      "dataset": jsondata,
        "events": {

                "dataPlotClick": function (eventObj, dataObj) {
                console.log(eventObj);
                }
                }
    }
  });
  salesHMChart.render();
});

任何建议如何解决这个问题？

谢谢

解决方案

将数据源作为单独的对象传递到图表的生命周期后，需要附加事件监听器，请查看示例以供参考

FusionCharts.ready(function() {
  var salesHMChart = new FusionCharts({
    type: 'heatmap',
    renderAt: 'chart-container',
    width: '100%',
    height: '350',
    dataFormat: 'json',
    dataSource: {
      "chart": {
        "caption": "Top Smartphone Ratings",
        "subcaption": "By Features",
        "xAxisName": "Features",
        "yAxisName": "Model",
        "showplotborder": "1",
