![过滤](https://linux22.com/image/356896/%E8%BF%87%E6%BB%A4.png)
我创建了一个基于 0 到 100 之间的值的条形图环境。
在我当前的设置中,数据是从文件读取并解析为单个的\addplot
。在现实世界中,我需要说明计划百分比与当前百分比之间的比较。为了从美学上说明这种差异,我需要单独的颜色,根据我的理解,这意味着单独的\addplot
宏。
更新:我的方法是无稽之谈。
我的方法是复制环境横条图示例代码中显示并创建另一个宏,名为水平双柱图。此环境将使用两个\addplot
调用:
过滤
- 首先筛选出解析并保存为宏的偶数
\addplot
行索引\jobname-barchart.export
\datatable
\pgfplotstableread
- 第二个
\addplot
过滤掉奇数行索引解析并保存为\jobname-barchart.export
宏\datatable
\pgfplotstableread
格式化
- 每个偶数行索引都是一个
\addplot
具有颜色的orange
。 - 每个奇数行索引都是一个
\addplot
带有颜色的blue!65!black
。
伪代码
我需要类似x index filter/.code=
按行索引过滤表值的功能。我认为条形图对齐后,再次读取数据时,`yticklabels 的名称相同。我不确定这在后台是如何工作的(目前)。
\tikzset{style-addplot-color1/.style={draw=none,fill=blue!65!black}}% addplot bar format
\tikzset{style-addplot-color2/.style={draw=none,fill=orange}}% addplot bar format
\newenvironment{horizontaldualbarchart}
{\VerbatimOut{\jobname-barchart.export}}
{\endVerbatimOut
% Inject BODY into pgfplotstableread
\pgfplotstableread[col sep=comma, header=false]{\jobname-barchart.export}{\datatable}
% Use \datatable for plot data
\begin{tikzpicture}
\begin{axis}[horizontalbarchartstyle]
\addplot [style-addplot-color1] table [col sep=comma, y expr=\coordindex, x=0, x index filter/.code{\ifeven\numexpr\coordindex\relax\def\pgfmathresult{}\fi] {\datatable};
\addplot [style-addplot-color2] table [col sep=comma, y expr=\coordindex, x=0, x index filter/.code{\ifodd\numexpr\coordindex\relax\def\pgfmathresult{}\fi}] {\datatable};
\end{axis}
\end{tikzpicture}
}%
伪输出
\addplot
如果我仅添加另一个具有不同样式定义的,但它读取所有相同的行(无过滤),它看起来会是这样的。

答案1
只需在数据中添加另一列,然后x index
为这两个\addplot
设置适当的值。请注意,我设置xbar={1pt}
为减小间距,并将减小到bar width
4mm。还请注意,您的设置text width=.4\textwidth
会将的边界框扩展tikzpicture
很多,因此,除非您的标签很长,否则我会将其删除。
