Title

How to draw a dual-axis chart

Describe

What methods can be used to draw a chart with two axes like this?

Solution

In VChart, you can add a right axis and bind the corresponding series to achieve this. Refer to the demo: https://visactor.io/vchart/demo/combination/dual-axis。

Code Example

const spec = {
  type: 'common',
  seriesField: 'color',
  data: [
    {
      id: 'id0',
      values: [
        { x: '周一', type: '早餐', y: 15 },
        { x: '周一', type: '午餐', y: 25 },
        { x: '周二', type: '早餐', y: 12 },
        { x: '周二', type: '午餐', y: 30 },
        { x: '周三', type: '早餐', y: 15 },
        { x: '周三', type: '午餐', y: 24 },
        { x: '周四', type: '早餐', y: 10 },
        { x: '周四', type: '午餐', y: 25 },
        { x: '周五', type: '早餐', y: 13 },
        { x: '周五', type: '午餐', y: 20 },
        { x: '周六', type: '早餐', y: 10 },
        { x: '周六', type: '午餐', y: 22 },
        { x: '周日', type: '早餐', y: 12 },
        { x: '周日', type: '午餐', y: 19 }
      ]
    },
    {
      id: 'id1',
      values: [
        { x: '周一', type: '饮料', y: 22 },
        { x: '周二', type: '饮料', y: 43 },
        { x: '周三', type: '饮料', y: 33 },
        { x: '周四', type: '饮料', y: 22 },
        { x: '周五', type: '饮料', y: 10 },
        { x: '周六', type: '饮料', y: 30 },
        { x: '周日', type: '饮料', y: 50 }
      ]
    }
  ],
  series: [
    {
      type: 'bar',
      id: 'bar',
      dataIndex: 0,
      label: { visible: true },
      seriesField: 'type',
      dataIndex: 0,
      xField: ['x', 'type'],
      yField: 'y'
    },
    {
      type: 'line',
      id: 'line',
      dataIndex: 1,
      label: { visible: true },
      seriesField: 'type',
      xField: 'x',
      yField: 'y',
      stack: false
    }
  ],
  axes: [
    { orient: 'left', seriesIndex: [0] },
    { orient: 'right', seriesId: ['line'], grid: { visible: false } },
    { orient: 'bottom', label: { visible: true }, type: 'band' }
  ],
  legends: {
    visible: true,
    orient: 'bottom'
  }
};

const vchart = new VChart(spec, { dom: CONTAINER_ID });
vchart.renderSync();

// Just for the convenience of console debugging, DO NOT COPY!
window['vchart'] = vchart;</br>
