如何在Google图表中插入列

Question

var options = {     高度：300，  title：“按价值排名前5位的债务人”，

条形图：'vertical'，//材质条形图必需。

      legend:  { position: 'bottom' }

};         var chart = new google.visualization.BarChart（document.getElementById（“ ChartNoCallCenterCollections2”）））

    //Listen for error message and blank out
    google.visualization.events.addListener(chart, 'error', function (googleError) {
        google.visualization.errors.removeError(googleError.id);
        document.getElementById("error_msg").innerHTML = "Message removed = '" + googleError.message + "'";
    });

    //var options1 = $.extend({}, optionslight, options);

    google.visualization.events.addListener(chart, 'select', selectHandler);   


    for (var i = 0; i < data.getNumberOfRows(); i++) {

            data.insertColumn(3, string, 'color: #42c698' );

     }

  var csv = google.visualization.dataTableToCsv(data);
  alert(csv);

  chart.draw(data, options);
