ggplot(iris_gathered, aes(reorder_within(Species, value, metric), value)) + geom_bar(stat = 'identity') + #scale_x_reordered() + facet_wrap(~ metric, scales = "free_x") Now, that’s beautifully done with a change in function. If you’re intereted more in Data Visualziation, Her...
The dplyr functionarrange()can be used to reorder (or sort) rows by one or more variables. Reorder rows by Sepal.Length inascendingorder my_data %>% arrange(Sepal.Length) ## # A tibble: 150 x 5 ## Sepal.Length Sepal.Width Petal.Length Petal.Width Species ## <dbl> <dbl> <dbl> <...
fct_reorder2()按与最大x值关联的y值对因子进行重新排序。由于线条颜色与图例对齐，因此这使图更易于...
