Seemingly inspired by the traditional thermometer charts and progress bars found in many dashboards, the bullet graph serves as a replacement for dashboard gauges and meters.
Bullet graphs were developed to overcome the fundamental issues of gauges and meters: they typically display too little information, require too much space, and are cluttered with useless and distracting decorations.
Bullet graphs can be created in R (programming language) using the bulletgraph() function developed by Marco Torchiano.
Below is an example of R code using the bulletgraph() function to create a black-and-white and colored bullet graph.
For each example: Bullet graphs may be horizontal or vertical and may be stacked to allow comparisons of several measures at once.
