两个xAxes水平条形图Charts.js

??????

xAxisID: 'x2'为第二个数据集设置，如下所示：

datasets: [{
      ...
   }, {
      label: "$Money",
      backgroundColor: "rgba(55,99,132,0.2)",
      borderColor: "rgba(255,99,132,1)",
      borderWidth: 1,
      hoverBackgroundColor: "rgba(55,99,132,0.4)",
      hoverBorderColor: "rgba(255,99,132,1)",
      data: [265, 459, 320, 181, 456, 555, 1040],
      xAxisID: 'x2',
   }]

??????

设置type: 'linear'和position: 'bottom'作为第二个x轴，如下所示：

xAxes: [{
         ...
      }, {
         id: 'x2',
         type: 'linear',
         position: 'bottom',
         gridLines: {
            display: false
         }
      }]

      ...

xAxes: [{
