我目前正在尝试创建一个图表,y 轴上有对数刻度。这基本上可行,只是值是nodes near coords
错误的。没有ymode=log
它,例如 20551 显示为标签。有ymode=log
它显示 9.93。是否有可能获得线性模式的行为?(因此它再次显示 20551 而不是 9.93)
是否可以使图例自动居中?
\begin{tikzpicture}
\begin{axis}[
width=0.8\textwidth,
ybar,
enlargelimits=0.15,
ylabel={\#Pathes},
ymode=log,
log ticks with fixed point,
xlabel={Test},
symbolic x coords={1 - 10, 11 - 100, 101 - 1000, 1001 - 10000, >10000},
xtick=data,
nodes near coords={\pgfmathprintnumber{\pgfplotspointmeta}},
nodes near coords align={vertical},
legend style={at={(0,-2.5em)}, draw=none, anchor=north, legend columns=-1, legend style={/tikz/every even column/.append style={column sep=0.5cm}}}
]
\addplot coordinates {(1 - 10, 20551) (11 - 100, 19784) (101 - 1000, 2436) (1001 - 10000, 149) (>10000, 12)};
\addplot coordinates {(1 - 10,4) (11 - 100,4) (101 - 1000,4) (1001 - 10000, 0) (>10000, 0)};
\legend{used,understood,not understood}
\end{axis}
\end{tikzpicture}

想要的输出:
答案1
您可以将legend
其置于0.5
代表每个轴中点的位置(无单位)。您也可以将其置于图例锚点。
