最小值、最大值和平均值条形图

Question

我正在制作一个图表，其中包含一组类别的最小值、最大值和平均值。我的灵感来自图片 2。在上一个问题问，我已经能够做出图 1 中所示的效果。

有没有办法将误差线的末端改为其他形状（正方形、圆形），就像图 2 中那样？

有没有办法添加标签来显示哪些值是最大值、最小值和平均值，如图 2 所示？（“Landsgjennomsnitt” = 平均值，“... høyest andel” = 最大值，等等）

有没有办法在每个条形的最大值和最小值旁边添加小文本？如图 3 所示。

Answer 1

由于您似乎还想要图例条目，最简单的选择可能是添加相应的图。
