无法读取 pgfplots 条形图的文本标签

我已经开始使用 pgfplots，可以绘制所有数据都是数字的散点图，但我对 xlabel 是文本的条形图却毫无办法。我尝试在手册和这里找到解决方案，但似乎都不起作用。我试图得到一个堆叠的 ybar，每个条形代表一个年度季度，条形由不同的贡献组成，但在绝望中，我很乐意只绘制第一列数据。以下是我得到的，但我收到错误，例如“索引为 1 的请求列表条目\datatable太大；此列表元素不足。”。有人能告诉我前进的方向吗？注释行也试过了。

\usepackage{pgfplotstable}
\pgfplotsset{compat=1.9}

这会是您想要的吗？要绘制堆叠的 ybar，请ybar用替换ybar stacked并添加更多addplot命令y=stationary，等等。还可以删除ymax=210或重置它。或者以更简洁的方式自动执行，如第二张图所示。

\foreach \i in {Electricity,Stationary,Transport,Fugitive,Industrial,Agriculture,Waste}{%
\addplot table [x expr=\coordindex, y=\i] {\datatable};}
