我有以下图片
如您所见,点 $A、B、C$ 有衬线。我希望它们没有衬线。我更改了\tkzLabelPoints
? 的字体。(font=\sffamily\sansmath
不起作用)

答案1
点的标签是 TikZ 节点,你可以\tkzLabelPoints
像普通节点一样添加选项,因此\tkzLabelPoints[below,font=\sansmath](A)
对单个标签执行此操作。要为所有点标签设置此功能,你可以使用以下方式修改label style
用于它们的样式:
label style/.append style={font=\sansmath}
已添加到tikzpicture
选项中。
