Data Visuazlization Course: Histogram Homework (Age Distribution of Survey Participants) --> Python and R

Question

Hello, Can someone please advise on how to add the the bin interval labels to show on the x-axis in both Python and R : -> I.e instead of X axis labels shown as 20 -- 40 -- 60 -- 80 --> How can we edit it to show something along the lines in Excel or Tableau as follows: [18,24] (24,30] (30-36] ....up to (72, 78] My attempt at a solution in R was adding a Labels variable with the bin intervals as strings:

agelabels <- c("[0, 24]","(24, 30]","(30, 36]","(36, 42]","(42, 48]","(48, 54]","(54, 60]",               "35-39","40-44","45-49","50-54","55-59","60-64","65-69",
               "(60, 66]","(66, 72]","(72+ ]")

But I cant figure out where in ggplot to display the labels (something like aes(label = agelabels)) ?! Best regards, Matt

Hi Matt, thanks for reaching out! For R studio what if you tried something along these lines: real_estate$interval <- cut(real_estate$Price, seq (0, 550, by = 50)) // this essentially splits the original variable into intervals, which you then plot with a histogram new_hist <- ggplot (real_estate, aes(interval)) +
geom_histogram(stat = "count") Best, 365 Eli
