lineRange is a custom series for Apache ECharts. It's typically used to show the range of data.

Source Code

Usage

Browser Environment

For browser usage, use the auto-registration version that automatically installs the custom series when loaded:

<script src="./node_modules/echarts/dist/echarts.js"></script>
<script src="./node_modules/@echarts-x/custom-line-range/dist/line-range.auto.js"></script>
<script>
  // No need to call echarts.use(), automatically registered
  const chart = echarts.init(...);
  const option = {
    series: [{
      type: 'custom',
      renderItem: 'lineRange',
      // ...
    }]
  }
  chart.setOption(option);
</script>

See examples for more details.

UMD (Universal Module Definition)

For environments that need manual registration or when using AMD/CommonJS loaders:

// CommonJS
const echarts = require('echarts');
const lineRangeInstaller = require('@echarts-x/custom-line-range');
echarts.use(lineRangeInstaller);
const chart = echarts.init(...);

const option = {
  series: [{
    type: 'custom',
    renderItem: 'lineRange',
    // ...
  }]
}
chart.setOption(option);

See examples for more details.

ESM (ES Modules)

For modern module bundlers or native ES module environments:

npm install @echarts-x/custom-line-range

import * as echarts from 'echarts';
import lineRangeCustomSeriesInstaller from '@echarts-x/custom-line-range';

echarts.use(lineRangeCustomSeriesInstaller);
const chart = echarts.init(...);

const option = {
  series: [{
    type: 'custom',
    renderItem: 'lineRange',
    // ...
  }]
}
chart.setOption(option);

See examples for more details.

API

series.data

The data of the series is an array of arrays.

option = {
  xAxis: {
    data: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'],
    type: 'category'
  },
  yAxis: {
    type: 'value'
  },
  series: [{
    type: 'custom',
    renderItem: 'lineRange',
    data: [
      [0, 10, 20],
      [1, 20, 30],
      [2, 30, 40],
      [3, 40, 50],
      [4, 50, 60],
      [5, 60, 70],
      [6, 70, 80],
    ],
    encode: {
      x: [1, 2],
      y: 0,
      tooltip: [1, 2]
    }
  }]
};

The first element of the sub-array is the x value. The second element is the starting y value, and the third element is the ending y value. If you want to make a vertical lineRange chart, you can swap the x and y in the above example (including encode).
