Hexbin chart and scatterplot with ggplot2


This post explains how to build a hexbin chart with a scatterplot on top using R and ggplot2. It is an addition to the page about 2d density plot with ggplot2.

2d density section Data to Viz

This plot extends the concepts described in the 2d density chart with ggplot2 document. It simply illustrates that a scatterplot can be added on top of the 2d density chart.

Thanks Christian Jacob for this submission. 

# library
library(ggplot2) 

# data
sample_data <- data.frame(x_values = 1:100 + rnorm(100,sd=20), y_values = 1:100 + rnorm(100,sd=27)) 

#plot
ggplot(sample_data, aes(x_values, y_values)) +
  stat_density2d(geom="tile", aes(fill = ..density..), contour = FALSE) + 
  geom_point(colour = "white")
