pgfplots：绘制百分比总和的面积（类似'ybar stacked'，但为面积样式）

pgfplots：绘制百分比总和的面积（类似'ybar stacked'，但为面积样式）

抱歉，标题不对，但我不知道如何正确解释我的问题。

我想要一个填充面积图，类似于 pgfplots 手册第 4.4.9 章（面积图），但以总和百分比作为值。

因此，我想总结一下 2005 年等的所有百分比值。

效果ybar stacked很好，但我希望填充区域也能如此。

这是一个可以工作的最小示例，它首先创建 ybar 堆叠，然后尝试创建 ybar 堆叠区域，但没有按预期工作：

\documentclass[a4paper,11pt,twoside]{memoir}
\usepackage{pgf}                    
\usepackage{tikz}                   % tikz graphics
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\usepgfplotslibrary{dateplot}

\begin{document}

您几乎已经拥有它了，除了您缺少需要\closedcycle添加到\addplot命令末尾的命令以便正确填充曲线下的区域：

\begin{tikzpicture}     
    \begin{axis}[
            stack plots=y,
            area style,         
            xlabel={Year},
            ylabel={\%},            
            enlarge x limits=false,
            enlarge y limits=upper,         
            legend pos=outer north east,            
            x tick label style={/pgf/number format/1000 sep=},          
        ]
        \addplot table [x=Year, y=1] {\data} \closedcycle;
        \addplot table [x=Year, y=1.1] {\data} \closedcycle;             
        \addplot table [x=Year, y=1.2] {\data} \closedcycle;
        \addplot table [x=Year, y=1.3] {\data} \closedcycle;
        \addplot table [x=Year, y=1.4] {\data} \closedcycle;     
        \end{axis}
\end{tikzpicture}

附注：如果您提供ybar stacked选项axis，则无需添加ybar到每个系列。这是自动设置的。
