笔画-达沙雷不能与角6结合。

Question

我用了这个角度为6的图表，我在这个图表上遇到了一些冲突，我试图绑定数据，但是我做不到，它不能正常工作，

这个stroke-dasharray="5, 100"给我取代了这个stroke-dasharray="{{this.master.locationVsStatusMap.size}}, 100"

stackblitz

有人知道怎么做正确吗？

提前感谢！

Answer 1

尝试属性绑定

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

Answer 2

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

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