![左下角出现虚假点,与森林相伴](https://linux22.com/image/398522/%E5%B7%A6%E4%B8%8B%E8%A7%92%E5%87%BA%E7%8E%B0%E8%99%9A%E5%81%87%E7%82%B9%EF%BC%8C%E4%B8%8E%E6%A3%AE%E6%9E%97%E7%9B%B8%E4%BC%B4.png)
我在画树时遇到了一个非常奇怪的问题forest
。在每棵树的左下角,我都会看到这个虚假的、错误的点。
以下是一个例子:
\usepackage{pgfplots}
\pgfplotsset{width=12cm,compat=1.10}
\pgfmathdeclarefunction{gauss}{2}{%
\pgfmathparse{1/(#2*sqrt(2*pi))*exp(-((x-#1)^2)/(2*#2^2))}

看到西南角的那个点了吗?我的文档中每棵树上都有这个点。我不知道如何去掉它。
谢谢你!
