Area chart

An area chart represents the evolution of a numeric variable. It is very close to a line chart. This section displays many examples built with R and ggplot2. Have a look at if you want to learn more about area chart theory.

Note on area chart

This section is tightly linked with other sections. A line chart is the same but doesn't fill the surface between the line and the X axis. A connected scatterplot is almost the same thing, but each observation is represented as a dot. More generally, the time series section can interest you.

Step by step with ggplot2

ggplot2 allows to draw line charts thanks to the geom_line() function. It expects as input a data frame with 2 numeric variables, one displayed on each axis. Start your journey with the most basic line chart.

Interactive version: dygraph

The dygraph package is dedicated to time series visualization. It offers zooming, hovering, minimaps and much more. Visit the time series section that is dedicated to it for more.

Step by step with base R

In base R, the combination of the plot() and the polygon() functions allows to build quality area charts.
