SVG将dasharray定位在顶部

我想得到一个' T形'在SVG Circle的顶部,但似乎无法正确显示它。我使用了 stroke-dasharray 来分割圆圈,但是我只能将它们放在右侧,理想情况下是将它们放在顶部,从而创造出来。 T形'。

有人可以指导我朝正确的方向前进吗?

"开始"圆圈位于3点钟位置。所以要定位" T"在顶部圆圈周围3/4处,需要从较长的第一个虚线段开始。

               stroke-dasharray: 547, 60.38, 110.69, 60.38, 664.16;

另一种选择是使用变换将圆圈旋转到正确的位置,但这通常比它的价值更麻烦。

或者您可以将<circle>替换为<path>。然后让路径从圆圈中的稍后位置开始。例如,我在下面的示例中从左侧(9 o&#39;时钟)开始。
