@cwtgogo convertToPixel is a method of echartsInstance. You can get echartsInstance from (chartInit) event.

For example:

<div echarts class="demo-chart" [options]="chartOptions" (chartInit)="onChartInit($event)"></div>

onChartInit(ec) {
  this.myChart = ec;
  this.myChart.convertToPixel('geo', [128.3324, 89.5344]);
}

你好，请问用'graphic '拖动线，你成功了吗？我对照echarts官方示例，在angular上还是不行。

I am having trouble implementing this as well.
