问题描述
我已经使用Amcharts绘制了一些面积图，但想分别给每个线段（线系列）上色。
我已经在一个片段中添加了propertyFields进行测试，但是无法显示测试颜色（黑色），下面是图表的完整代码，位于div ID＃chartdiv1中。
let chart = am4core.createFromConfig({

已删除底色，因此可以单独设置所有图表（段）bg颜色。
但是在文档中找不到如何使用基于json config的图表设置实际颜色的方法吗？
如何将SL6段颜色设置为黑色进行测试，然后在其他段上重复不同的颜色？
SL6段位于底部的右侧。
工具提示很好，只想更改图表段的颜色？
谢谢
