[Bug] Brush unable to detect exact selected value in Funnel, Radar & Gauge about echarts HOT 2 OPEN

Wonder about your use case... Typically brush is not used on these types of charts.
Demo on how to funnel select with selectchanged.

from echarts.

Use case: When there are a lot of values, say >20, in legend and user wants a subset of them, then instead of toggling the items in legend, user can make a rectangular selection of desired values, which will also update the visibility of items in the legend.

Typically brush is not used on these types of charts.

@helgasoft , Please elaborate. Are you saying this regarding echarts? what do you mean by these "types of charts". Please include references, if any.

Thankyou!! This is great!!! didn't know 2 events can be used together. It solves part of my issue.
Using the same example, say I click on the third and fourth item in the funnel, is it possible to make others "visually disabled" ( or changing there color to grey , but still click-able ) without using a for-loop through the series-data and adjusting opacity of elements that are not selected.
