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]

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？

TITLE

Line chart settings visualMap.pieces 2000 segments. Is there any solution to configure dataZoom to zoom in and out?

BODY

Version

5.1.2

Steps to reproduce

If visualMap.pieces has too many segments, it will cause zooming in and out. The more segments, the more cards, about 1200 segment meeting cards

What is expected?

If visualMap.pieces has too many segments, dataZoom will be optimized so that zooming in and out will not freeze

What is actually happening?

dataZoom zoom in and out the meeting card

---

My requirement is that the color of each segment of the chart is different. Starting from the first point, P0 (the previous point) is compared with P1 (the next point), P1> P0 red, P1 <P0 green, P1 = P0 Press P0 to point the color

Is there any other solution besides visualMap.pieces?

@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

@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。
