Data Visualization Basics For Dashboards
Part 2

For two reasons, it is inappropriate to use a gauge for KPIs like average revenue per employee. Firstly, such KPIs are only required to be calculated once in a quarter, so they cannot be classified as variable parameters. Secondly, these parameters do not influence day to day operations - hence, it is not necessary to monitor such data on a regular basis.

Types of gauges:

 Gauges are of many different types, and each type of gauge has certain functional implications. This means  that each type of gauge can be used as an indicator only for parameters - that have certain specific properties. So, selecting the right kind of gauge for a particular parameter is a crucial aspect of dashboard designing.

Following is a brief description of some popular types of gauges:

Angular Gauge

The angular gauge is ideal for indicating the status of a parameter whose value falls within a well defined range. Since, an angular gauge makes the occurrence of change noticeable, it should be used for parameters that are susceptible to very frequent change.

Angular Gauge

Linear Gauge

Like the angular gauge, a linear gauge is also meant for parameters whose value falls within a well defined range. However, in case of a linear gauge, the change should be less frequent.
