Streamgraph | the R Graph Gallery

Step by step: the streamgraph package.

It is relatively straightforward to build a streamgraph in R thanks to the streamgraph package.

Most basic streamchart

The most basic streamchart you can build with R and the streamgraph package.

Change offset

By default a streamchart is displayed all around a horizontal line. You can change that thanks to the offset option

Change shape

Leave the smooth and rounded option to get something similar to a stacked area chart or to a stacked barplot.

Change color

Several ways to change the color palette used on the chart.

Interactivity

The streamgraph package is a html widget. It means that your output will automatically be interactive. Hover a group to highlight it, get its name and its exact value. If for some reason you need to export it to png or pdf, it is possible thanks to the webshot package.
