如何为amChart设置x轴和y轴名称的标题？

Question

在amChart中，如何为图表的X轴和Y轴标题设置自定义名称（字符串）？

（水平轴和垂直轴）

var chart = AmCharts.makeChart( "chartdiv", {
  "type": "xy",
  "pathToImages": "http://www.amcharts.com/lib/3/images/",
  "dataProvider": chartData,
  "mouseWheelZoomEnabled": true,
  "graphs": [ {
    /*"bullet": "circle",
    "bulletSize": 8,*/
    "lineAlpha": 1,
    "lineThickness": 2,
    "fillAlphas": 0,
    "xField": "x",
    "yField": "y",
  } ],
} );

您可以为每个轴使用title参数。但是，您需要将valueAxes定义添加到图表配置中。即使它们只包含title参数。

var chart = AmCharts.makeChart( "chartdiv", {
  "type": "xy",
  "pathToImages": "http://www.amcharts.com/lib/3/images/",
  "dataProvider": chartData,
  "mouseWheelZoomEnabled": true,
  "graphs": [ {
    /*"bullet": "circle",
    "bulletSize": 8,*/
    "lineAlpha": 1,
    "lineThickness": 2,
    "fillAlphas": 0,
    "xField": "x",
    "yField": "y",
  } ],
  "valueAxes": [ {
    "position": "left",
    "title": "Y axis"
  }, {
    "position": "bottom",
    "title": "X axis"
  } ]
} );
