G2

Load data from a url specified by the value option. G2 will infer the data type from the file extension by default. The format of input data can also be specified by the format option.

// Spec
chart.options({
  type: 'point',
  data: {
    type: 'fetch',
    value: 'https://gw.alipayobjects.com/os/antvdemo/assets/data/scatter.json',
  },
});

// API
chart.data({
  type: 'point',
  data: {
    type: 'fetch',
    value: 'https://gw.alipayobjects.com/os/antvdemo/assets/data/scatter.json',
  },
});

开始使用

(() => {
  const chart = new G2.Chart();

  chart.options({
    type: 'point',
    data: {
      type: 'fetch',
      value:
        'https://gw.alipayobjects.com/os/antvdemo/assets/data/scatter.json',
    },
    encode: {
      x: 'weight',
      y: 'height',
      color: 'gender',
    },
  });

  return chart.render().then((chart) => chart.getContainer());
