It shouldn't call `getDataURL` immediately after `setOption` for the rendering is asynchronized.
Instead, we should listen to the [`finished`](https://echarts.apache.org/next/en/api.html#events.finished) event like this,
```js
myChart.on('finished', function() {
img.src = myChart.getDataURL();
});
```
