我正在写一个图形，我需要与每个点相关的误差线，我有以下内容：
\begin{tikzpicture}
\datavisualization[visualize as smooth line/.list={lac10},
scientific axes={clean},
legend={at={(0.5,5)},anchor=north west},
x axis={length=50mm,ticks={major={tick text padding=.5ex},node style={scale=1},minor steps between steps=1,step=2},label={Days}, include value={0,22}},
y axis={length=50mm,ticks={major={tick text padding=.5ex},node style={scale=1},minor steps between steps=1,step=3},label={Laccase activity [U/g$_{ds}$]}, include value={0,33},},
lac10={style={mark=*,mark size=1pt,mark options={solid,black},color=black},label in legend={text={\tiny 10.0 g}}},
]
data[set=lac10]{
x,y,ey
0, 0, 0
2, 0.2559, 0.0603
4, 3.6438, 0.2075
6, 8.0834, 0.6724
8, 9.3111, 0.7168
10, 3.3177, 0.2275
12, 1.6083, 0.0820
14, 26.0593, 1.5983
16, 29.4135, 1.5789
18, 24.3474, 1.3521
20, 13.6993, 1.0829
};
\end{tikzpicture}
最后我没有得到错误栏，只得到了要点，我想知道我错过了什么或者我必须在代码中添加什么。我非常感谢你们的所有建议。

查看手册，我找不到不编写自定义可视化工具就轻松完成此操作的方法。
然而，PGFplots 可以很容易地产生相当类似的结果：
\documentclass[tikz,margin=5]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.14}
\begin{document}
\begin{tikzpicture}
\begin{axis}[ymin=0, ymax=33,
ytick={0,3,...,33}, ytick align=outside, ytick pos=left,
xtick={0,2,...,22}, xtick align=outside, xtick pos=left,
xlabel=Days,
ylabel={Laccase activity [U/g$_{ds}$]},
legend pos=north west,
legend style={draw=none}]
\addplot+[
black, mark options={black, scale=0.75},
smooth,
error bars/.cd,
y fixed,
y dir=both,
y explicit
] table [x=x, y=y,y error=error, col sep=comma] {
x, y, error
0, 0, 0
2, 0.2559, 0.0603
4, 3.6438, 0.2075
6, 8.0834, 0.6724
8, 9.3111, 0.7168
10, 3.3177, 0.2275
12, 1.6083, 0.0820
14, 26.0593, 1.5983
16, 29.4135, 1.5789
18, 24.3474, 1.3521
20, 13.6993, 1.0829
};
\addlegendentry{10.0 g}
\end{axis}
\end{tikzpicture}
\end{document}
