Bullet Charts are small one-series charts which are predominantly used to compare a single measure to some other measures that are intended to enrich the meaning of the first one, and can display its ranges of performance, e.g. “poor”, “satisfactory” and “good” or “low”, “average” and “high”. These charts were developed and designed by Stephen Few; they are inspired by thermometer charts and progress bars, which can be found in many dashboards.
This example is a table with 14 bullets, each showing the actual amount of vitamins (bars) and its normal daily intake (bullets). Vitamin names are written under the bullets. These Charts have no tooltips. Due to specific of this particular sample, ranges are disabled, so we can see only the ratio between the actual and the target values.
