![如何为来自外部文件的图表中的条形组着色?](https://linux22.com/image/280726/%E5%A6%82%E4%BD%95%E4%B8%BA%E6%9D%A5%E8%87%AA%E5%A4%96%E9%83%A8%E6%96%87%E4%BB%B6%E7%9A%84%E5%9B%BE%E8%A1%A8%E4%B8%AD%E7%9A%84%E6%9D%A1%E5%BD%A2%E7%BB%84%E7%9D%80%E8%89%B2%EF%BC%9F.png)
我有一张显示条形和误差线的图表,数字来自外部.dat,只是黑白色。
以下是我到达那里的方式:
\documentclass[12pt]{report}
\usepackage{pgfplots}
\begin{figure} [ht]
\begin{tikzpicture}
\begin{axis}[xtick pos=left, unbounded coords=jump, scale=1.97, ybar, bar width=8pt, ylabel=$F_{Bruch}$\,${[N]}$,xtick=data,xticklabels from table={data.dat}{amount}]
\addplot [error bars/.cd,y dir=both,y explicit]
table[x expr=\coordindex,y=FB,y error =sFB]{dataEB.dat};
\end{axis}
\end{tikzpicture}
\vspace{-25pt}
\small
\begin{tabbing}
xxxxxxxxxxxxx\=xxxx\kill
\>\begin{tabular}[htbp]{*{6}{@{}c}}
$\underbrace{\;\;\;\;\;\;\;\;\;\;\;\;\;\;}$ & \;\;\;\;\,$\underbrace{\;\;\;\;\;\;\;\;\;\;\;\;\;\;}$ & \;\;\,$\underbrace{\;\;\;\;\;\;\;\;\;\;\;\;\;\;}$ & \,$\underbrace{\;\;\;\;\;\;\;\;\;\;\;\;\;\;}$ & \,$\underbrace{\;\;\;\;\;\;\;\;\;\;\;\;\;\;}$ & \;$\underbrace{\;\;\;\;\;\;\;\;\;\;\;\;\;\;}$ \\
PEL80\,L & \;\;\;\;PEL80\,B & \,\;\;\;\;PEL90A\,L & \;\;\;PEL90A\,B & \;\;\,PEL90B\,L & \;\;PEL90B\,B \\
\end{tabular}
\end{tabbing}
\caption{bla bla}
\end{figure}
我必须调整原始数据,以便误差线处于正确的位置(必须插入几个纳米才能获得我的间距)。
我的问题如下:如何让不同组的条形图具有不同的颜色(例如 PEL80L=红色、PEL80B=绿色,...)?有没有更聪明的方法将这些括号放在组下方?
