Sorting DataFrame for ggplot barplot [duplicate]

问题

This question already has answers here:

Order Bars in ggplot2 bar graph (12 answers)

Closed 2 years ago.

I have a data frame df1 and want to draw a barplot of AccountExecutive and their corresponding ClearRate where the bars are arranged so that it is decreasing from left to right.

I tried this code but the resulting graph still reflects AccountExecutive order as it appears in df1

ggplot(arrange(df1, -ClearRate), aes(x = AccountExecutive, y = ClearRate)) +
  geom_bar(stat="identity")

Can anyone help me correcting this code?

NOTE: Not a duplicate of the previous question because that one asks for an arbitrary positioning of the x axis labels. This question asks how to sort x-axis labels considering their y-axis values.

回答1:

Try this one the code below should reorder AE according to clearance rate

ggplot(df1,aes(x=reorder(AccountExecutive,-ClearRate),y=ClearRate))+geom_bar(stat"identity")

here is the more about reorder function Reorder bars in geom_bar ggplot2
