Bullet Charts are a great way to present information and metrics. This slidedeck provides instructions on how to create Bullet Charts in a spreadsheet after you download the Aculocity Add In for Excel.
So if you want to compare performance of a metric e.g. Sales in two periods e.g. this year v’s last year (or target) on a continuum that also shows Poor, Ok and Good performance, a bullet chart could be very useful.
