![无法增加两条线之间的角度半径](https://linux22.com/image/365651/%E6%97%A0%E6%B3%95%E5%A2%9E%E5%8A%A0%E4%B8%A4%E6%9D%A1%E7%BA%BF%E4%B9%8B%E9%97%B4%E7%9A%84%E8%A7%92%E5%BA%A6%E5%8D%8A%E5%BE%84.png)
我希望角度标签 gamma 具有更大的半径,但该radius
参数不会改变任何东西。这是我的代码

答案1
该参数已命名angle radius
,而不是radius
,因此
\pic [draw, angle radius=1cm, ->, "$\gamma$", angle eccentricity=1.5] {angle = 2--11--22};
绘制类似内容的替代方法。请注意,该topaths
库由 TikZ 自动加载,因此您不必自己执行此操作。
