Version

4.2.1-rc1

Steps to reproduce

1、点击框选按钮
2、框选

What is expected?

大数据的散点图,期望能够实现框选功能

What is actually happening?

你好,由于我的散点图要渲染几十万甚至上百万的数据,使用了appendData进行分片段展示,但是对于这种情况,一点击框选按钮(brush)就重新渲染,一去框选还是重新渲染。请问针对大数据量的散点图,如何实现框选功能呢

为什么框选总是不停的重新渲染?能不能不重新渲染,直接实现框选?

目前选框的时候需要更新图形的样式,甚至更复杂的视觉编码

现在大数据量的散点图,框选有没有什么解决方案呢

自己写一个框选事件不就好了

dispatch一下Action就好了

能否提供详细一点的解决方案呢@SheStealsMyPenta

公司不允许,就是几十万个散点,点击框选按钮,就刷新。重写框选有什么思路吗?

@SheStealsMyPenta

你是指那个快捷的小按钮。点一下就刷新吗

@NingMengMeng

是的,框选的时候也刷新。就是不想刷新,直接框选

@lay-coder

监听,触发brushselected事件就暂停你的分片段展示不就好了

兄弟,这个问题最后怎么解决的?求指点

@Ovilia 你好,点击框选图标和框选的时候是否可以阻止重绘,大数据时候很影响体验

这个问题有解决方案吗?数据量大的时候,框选几乎是无法使用的,特别卡顿
