How to clear the box selection at the end of the onbrushEnd event when using vchart?

Question title

Problem description

I am using the @visactor/vchart chart library for chart development and encountered a problem. I need to clear the brush box at the end of the onbrushEnd event, but currently I have not found a suitable API to implement this requirement.

Solution

Currently, there is no API that directly corresponds to this requirement, but there is a relatively special implementation method that can solve this problem. The specific code is as follows:

cs.on('brushEnd', (params) => {
cs.getChart()?.getAllComponents().forEach(c => {
if(c.name === 'brush') {
c?._brushComponents?.forEach(c => c._container.incrementalClearChild())
}
})
})

The above solution is to retrieve all components and traverse them after triggering the'brushEnd 'event. If a component is named'brush', it will be cleared.
