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-stage/dist/index.auto.js"></script>
<script>
  // No need to call echarts.use(), automatically registered
  const chart = echarts.init(...);
  const option = {
    series: [{
      type: 'custom',
      renderItem: 'stage',
      // ...
    }]
  }
  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 stageInstaller = require('@echarts-x/custom-stage');
echarts.use(stageInstaller);
const chart = echarts.init(...);

const option = {
  series: [{
    type: 'custom',
    renderItem: 'stage',
    // ...
  }]
}
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-stage

import * as echarts from 'echarts';

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

const option = {
  series: [{
    type: 'custom',
    renderItem: 'stage',
    // ...
  }]
