[GitHub] [echarts] webywz opened a new issue #15740: 折线图设置 visualMap.pieces 2000个分段。配置dataZoom 放大缩小会卡，有什么方法解决吗？
webywz opened a new issue #15740:
URL: https://github.com/apache/echarts/issues/15740
### Version
5.1.2
### Steps to reproduce
visualMap.pieces 分段太多的话，会造成放大缩小卡顿。分段越多越卡，大概是1200个分段会卡
### What is expected?
visualMap.pieces 分段太多的话，dataZoom 做优化，放大缩小不会卡顿
### What is actually happening?
dataZoom 放大缩小会卡

我的需求是图表的每一段的颜色都不一样。
从第一个点开始，P0( 前一个点 ) 与 P1( 后一点 ) 做比较，
P1 > P0 红，
P1 < P0 绿，
P1 = P0 按P0 点颜色
除了visualMap.pieces 还有其他实现方案吗？

@pissang 我有尝试分成两个系列，但当数据点太多时，因为采样的关系，最终图形会有所变化。
> @webywz 如果只有红绿两个颜色，建议分成两个系列，绿色系列中的红色数据部分用`'-'`填充，同理红色系列

@webywz Please provide a minimum reproducible demo for the issue either with https://codepen.io/Ovilia/pen/dyYWXWM , https://www.makeapie.com/editor.html or https://codesandbox.io/s/mystifying-bash-2uthz.
*A minimum reproducible demo* should contain as little data and components as possible but can still illustrate your problem. This is the best way for us to reproduce it and solve the problem faster.
