我创建了以下图片
使用以下代码
\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{%
compat=newest,%
/pgf/number format/use comma,%
/pgf/number format/1000 sep={\,},%
/pgf/number format/min exponent for 1000 sep=4}
\begin{document}
\begin{tikzpicture}
\begin{axis}[title={}, xlabel={}, ylabel={}, zlabel={},%
legend cell align=left]
\addplot[red, only marks]
coordinates {(23.0175,1.64554e-15)};
\addplot[brown, only marks]

\addplot[orange, only marks]

我想用虚线连接所有数据点。如果它们仅代表一个坐标的不同图形,是否可以实现这一点?
答案1
pgfplots
的scatter
选择似乎很有希望(第 4.4.10 节手动的)。
解决方案scatter
注释(我不喜欢的东西)
- 在我看来,每个标记的图例条目只有通过类别才可行。
- 这是非常明确的。

我不喜欢这个解决方案。
