Sample Charts > DialChart
The Dial or Gauge chart is often used to present a single value (maybe a benchmark index of company performance) in the context of an expected or desired range. The value on its own may mean very little (maybe our production plant made 23% rejects last week) until it is set in the context of the expected range (say 20% – 30% is normal, 30-40% is unusually poor, and so on). The dial chart can be set up with a range to cover the likely values, and a series of colored ‘zones’ to indicate the actions appropriate to each value – typically OK, Warning, Critical.
Dials are often grouped in the likeness of a dashboard or aircraft cockpit to give the user a degree of familiarity with the experience of monitoring the various instruments found in a vehicle or aeroplane.
