Event Handling

Users can trigger related events through their operation. To react on Mouse and other events, use echartsInstance:

/**
 * On Mouse Click
 */
echartsInstance.on('click', (params) => {
  notifySuccess(['Event', 'On Click']);
  ...
  echartsInstance.resize(); // to redraw visualization
});

/**
 * On Double Click
 */
echartsInstance.on('dblclick', (params) => {
  ...
  echartsInstance.resize();
});

For more examples and details, take a look at the official documentation Event and Action.
