我认为这是一个简单的修复，但我现在没有看到它。
我有四组数据集 (A、B、C、D)，但是在 x = 200 和 x = 800 处条形图未完全显示。
在此先感谢您的帮助。

回答后更新
谢谢Torbjørn T.，您的解决方案效果很好。感谢您指出我混淆了 pgfplot 和 TikZ 语法。
我对 pgfplot 和 TikZ 语法进行了一些基本且有用的研究这里（也许我应该早点这么做）。
添加更多栏目
也许这对其他人有用。
最后我想总共有 6 个条形图，但图表的宽度不会自动更新。因此我在轴选项中添加了以下内容：scale only axis，width=0.95\textwidth height=0.3\textwidth。

答案1
添加enlarge x limits={abs={100}}到axis选项中。
无关紧要的\addplot plot是混合pgfplots和 TikZ 语法，您只需要\addplot [<all the options>]。最后，当您在选项ybar中时axis，每个中都不需要它\addplot。
