Making a stacked bar plot based on ranges in R and plotly

Question

I want to create a stacked bar chart in R and plotly using iris dataset. In the x-axis, I want to set limits like iris_limits below in the code and the y-axis should contain all

Answer 1

Try using cut:

library(plotly)
iris$iris_limits <- as.numeric(cut(iris$Sepal.Length,3))
p <- plot_ly(iris, x = ~iris_limits, y = ~Sepal.Length, type = 'bar', name = 
               'Sepal') %>%
  layout(yaxis = list(title = 'Count'), barmode = 'group')
p

The grouping details:

> iris$Sepal.Length[iris$iris_limits==1]
 [1] 5.1 4.9 4.7 4.6 5.0 5.4 4.6 5.0 4.4 4.9 5.4 4.8 4.8 4.3 5.4 5.1 5.1 5.4 5.1 4.6 5.1 4.8 5.0 5.0 5.2 5.2 4.7 4.8
