Question

我想重新排序堆积的条形图数据点，以便在每个条形图中按照其总VALUE从最大到最小的COMPETITOR排序，而不是按字母顺序排序。

我生成数据以使用fct_reorder（注释掉的行）并且数据点被排序但标签不遵循更改的顺序。如何使图上的标签跟随并位于条形段中间的正确位置？

这是我的工作可重复示例，其中fct_reorder行被注释掉了。如果取消注释，数据点将被排序，但标签将保持在错误的位置。

Answer 1

我认为以下内容应该这样做：

ggplot(df, aes(x = reorder(CUSTOMER, -COMP_VALUE), y = VALUE))

按COMP_VALUE命令CUSTOMER列。

Answer 2

我评论了＃****＃****描述****`可以在堆积的条形图中对数据点和标签进行排序的行。现在他们按照COMPETITOR的总销售额订购，而不是按字母顺序排列。我承认我通过反复试验来实现它，这可能不是最佳答案。
