DENSITY PLOT

A density plot shows the distribution of a numerical variable. It takes only set of numeric values as input. It is really close to a histogram. Since it is a really common dataviz technique,

most of the dataviz libraries allow to draw it. Note that it is highly recommended to play with the bandwith argument in order not to miss a specific pattern in the data. Note that you can compare the

distribution of several variables plotting them on the same axis, using faceting or through a joyplot.

Input format

 

To represent a density, you need only one vector of numbers. It can be a list, or the column of a data frame.

If you have several numerical variable, you can plot several densities and compare them, or do a boxplot or violin plot.

Format 1: 1 numerical variable only.
