# OBIEE - Gauge View

A gauge view shows a single data value.

Due to its compact size, a gauge is often more effective than a graph for displaying a single data value.

Gauges identify problems in data.

A gauge usually plots one data point with an indication of whether that point falls in an acceptable or unacceptable range.

Thus, gauges are useful for showing performance against goals.

Depending on the data in the analysis, a gauge view might consist of multiple gauges in a gauge set.

For example, if you create a gauge view to show the sales data for the last twelve months, the gauge view consists of twelve gauges, one for each month. If you create one to show the total sales in the US, then the gauge view consists of one gauge.

A gauge or gauge set is displayed on a background, called the gauge canvas.

## 3 - Type

All gauges are 2-dimensional (2-D) with the exception of bulb gauges which can be either 2-dimensional or 3-dimensional (3-D). Their sizes can be small, medium, large, or a custom size.

### 3.1 - Dial

Shows data using a dial arc with one or more indicators that point to to where the data falls within predefined limits.

### 3.2 - Horizontal bar

Shows data using a horizontal bar that changes color to indicate whether the data is within predefined limits. The inner rectangle of the horizontal bar shows the current level of data against the ranges marked on an outer rectangle.

### 3.3 - Vertical bar

Shows data using a vertical bar that changes color to indicate whether the data is within predefined limits. The inner rectangle of the vertical bar shows the current level of data against the ranges marked on an outer rectangle.

### 3.4 - Bulb

Shows data using a circle that changes color to indicate whether the data is within predefined limits.

Bulb gauges are useful when you need to know what the status is, and not any indication of a specific value, or relative information about other threshold ranges.
