Dumbbell chart#

A dumbbell plot can be used to visualize two different values in time, or to show the difference between two different groups or viewpoints (e.g., one dot for male and another dot for female).

The dumbbell is a variant of the lollipop plot.

Getting started#

Dumbbell series requires loading the Highcharts and both highcharts-more and dumbbell.js modules.
