Yes, I also need this feature: connect func can set which action to connect.

Or can echarts support 'escapeConnect' to avoid connect when dispatchAction
chartInstance.dispatchAction({ type: 'legendSelect', name: 'test', escapeConnect: true });

What problem does this feature solve?

In some cases, only part of the action wants to be connected. Like the case in #13630

What does the proposed API look like?

The second parameter is a list of fired events.

echarts.connect([chart1, chart2], ['dataZoom', 'visualMap']);

I read source code, find this method to avoid be connected, you can try it.

chartInstance.dispatchAction({
  type: 'legendUnSelect',
  escapeConnect: true,
  batch: [
    {
      name: key,
      selected: legendsSelected,
    },
  ],
});

@14glwu Hi, I think escapeConnect is for inner usage. It's not convenient for users.
