[GitHub] [echarts] tamersalama opened a new issue #14258: Brush (lineX, lineX) doesn't work with line charts
tamersalama opened a new issue #14258:
URL: https://github.com/apache/echarts/issues/14258
### Version
5.0.2
### Reproduction link
[https://codepen.io/tamersalama/pen/mdOraGb?editors=1111](https://codepen.io/tamersalama/pen/mdOraGb?editors=1111)
### Steps to reproduce
1- Create a *line* chart with a horizontal selector (lineX) brush
2- Use the brush to select a data range
3- The onbrushselected event fires up normally, however the event parameters' dataIndex (`params.batch[0].selected[0].dataIndex`) returns an empty array
4- Changing the chart type to scatter or bar will result in a proper dataIndex being returned
### What is expected?
It's expected that the `dataIndex` for the selection to have an array of selected values
### What is actually happening?
dataIndex within `params.batch[0].selected[0].dataIndex` is empty

Thanks for the above trick @tamersalama
Also, `brushSelected` event doesn't seem to be documented. Will it be possible to add an entry for that in the docs?

Thank you for adding this a milestone.
As a workaround (in case anyone encountered the same issue) - I'm using `params.areas[0].coordRange` to get the selected range. Not perfect but could work is some cases.
