更改高级条形图的颜色（pgfplotstable）

根据这个精彩的答案，我制作了一个堆叠和聚集图：https://tex.stackexchange.com/a/55559/93892。但是，我想改变条形的颜色。最重要的是，我想将红色和蓝色改为灰色/黑色。每隔一列进行区分（以区分初始列和主列）可能很有趣，但这并不是至关重要的。

我尝试了几种方法，但都没有成功。我认为这应该相当简单，所以如果你们中有人能立即明白如何做到这一点，我将不胜感激。

这是命令fill=中的选项\addplot（您在代码中忘记了它 - 根据链接的答案，我猜到了您试图绘制的内容）。灰色阴影可以通过以下方式实现black=!50（提供介于黑色和白色之间的阴影）、black=!10（提供从黑色到白色的 10% 的阴影）等等。以下是示例：

\addplot[fill=black!10] table [x=X, y=Remaining] {\datatable}; \addlegendentry{Remaining}
\addplot[fill=black!60] table [x=X, y=Removed] {\datatable}; \addlegendentry{Removed}

将代码中的条目替换\addplot为上面的条目，并根据需要调整数字。
