我将此图表与角度 6 一起使用，我在此图表上遇到了一些冲突，我尝试绑定数据，但我不能这样做，它无法正常工作，

这个stroke-dasharray="5, 100"给我换了这个 stroke-dasharray="{{this.master.locationVsStatusMap.size}}, 100"

堆栈闪电战

任何人都知道如何正确地做到这一点？

提前致谢！

尝试属性绑定

attr.stroke-dasharray="{{this.master.locationVsStatusMap.size}}, 100"

分叉示例：https ://stackblitz.com/edit/angular-wqjlc5

使用样式绑定 - https://coryrylan.com/blog/angular-progress-component-with-svg

style.stroke-dasharray="{{varible}}, 100"
