Brush event data of echarts

[mswastik]

There is already on_point_click parameter in ui.echart function to make point click data from echart available in python. Is it also possible to make brush data available in python? Details of brush selection on echarts can be found at https://echarts.apache.org/en/option.html#brush.

Hi @mswastik!

Currently, ui.echart only supports point click events. Adding brush or even more events would be a great new feature.
Or maybe we find a way to generically support all events, but I'm not sure how.

Ideas, pull requests and other contributions are greatly appreciated. 🙂
