如何在移动或触摸设备上使用amcharts 3单击图例

如何解决如何在移动或触摸设备上使用amcharts 3单击图例

我正在使用Amcharts版本3，并在移动视图和Web视图上绘制一些图形，但无法在移动视图中单击图例。

我也尝试了事件监听器，但仍然只能在Web视图中单击才能获取事件。

$(document).ready(function() {
 function handleLegendClick(graph) {
        var chart = graph.chart;
        var hidden = graph.hidden;
        if (hidden) {
            chart.showGraph(graph);
        }
        else {
            chart.hideGraph(graph);
        }
       // return false so that default action is canceled
        return false;
    }
  var chartdata = [{
      "EntryDate": "2017-11-12T00:00:00","Propane": 575.0000,"Ethane": 1.7500,"FiscalPeriodText": "2017-Q4","polypropyleneLag": 1120.0000,"PPMargin": 310.00000,"PPMarginLag": 290.00000,"PPMarginHigh": 396.500000,"PPMarginLow": 343.2500000,"": 370,"PPMarginAvg": 311.250000,"PPMarginLagAvg": 300.000000,"PPMarginHighAvg": 408.750000,"PPMarginLowAvg": 354.3750000
    },{
      "EntryDate": "2017-11-19T00:00:00","polypropyleneLag": 1130.0000,"PPMarginLag": 300.00000,"PPMarginHigh": 406.500000,"PPMarginLow": 353.2500000,{
      "EntryDate": "2017-11-26T00:00:00","polypropyleneLag": 1150.0000,"PPMarginLag": 320.00000,"PPMarginHigh": 426.500000,"PPMarginLow": 373.2500000,"PPMarginLowAvg": 354.3750000
    }
  ];




  var chartbar;
  chartbar = AmCharts.makeChart('ChartDiv',{
    'type': 'serial','dataProvider': chartdata,'valueAxes': [{
      'id': 'v1','position': 'left','inside': false,'autoGridCount': false,'labelOffset': 15,'minHorizontalGap': 100,'gridCount': 8

});

.map_wrapper {

注意：我在移动视图中使用Bootstrap和CSS进行响应设计，一切正常，但是我无法单击图例，我尝试使用事件侦听器，但仍然无法从移动设备上单击图例来获取事件设备
