How to trigger a re-render of echarts?

To trigger a re-render of ECharts, you can use the following method:

1. You can use the setOption() method to update the chart by setting new options. This method allows you to change the data, style, and configuration options. For example:
2. Get the ECharts instance.

   Set a new option.

   Update the chart using the setOption() method.

3. Utilize the clear() method: By using the clear() method, you can clear the chart and then redraw it. For example:
4. // Get the ECharts instance
   var chart = echarts.init(document.getElementById(‘chart’));

   // Clear the chart
   chart.clear();

   // Redraw the chart
   chart.setOption(option);

5. Destroying a chart instance using the dispose() method and then recreating and rendering it. For example:
6. // Obtain an ECharts instance
   var chart = echarts.init(document.getElementById(‘chart’));

   // Destroy the chart instance
   chart.dispose();

   // Re-create and render the chart
   chart = echarts.init(document.getElementById(‘chart’));
   chart.setOption(option);

Please note that the “chart” in the above methods represents an instance object of ECharts, and “option” represents the configuration options for the chart.
