Gauge Chart

1) Gauge Chart is a versatile visualization tool used to represent progress towards a specific goal, depicted via a circular or semi-circular scale. Its importance lies in the ability to display key performance indicators such as completion rates or target achievements clearly and instantaneously. 

2) Gauge Charts are particularly beneficial in business environments where real-time data monitoring and quick decision-making are crucial. They provide a straightforward method to assess performance against predetermined thresholds, making them indispensable for dashboard analytics.

3) Application Scenario：The following figure shows the supported gauge styles in FineBI.

The gauge color is related to the fields in Color and Pointer Value.

The field in Color determines the value range which a color can represent. Then the system finds the corresponding mapping value in the value range based on the value of the field in Pointer Value. For example, yellow represents the value range 0-440, red represents the value range 440-880, and pink represents the value range 880-1320. If the pointer value is 1320, the gauge is displayed as yellow, red, and pink.

Take the percentage ring gauge as an example to illustrate this logic.

1. The pointer value is 1320. The following figure shows the colors of different value ranges.

2. The following figure shows the final effect.

Gauge Scale Hiding

To hide the scales of the multi-pointer gauge and the test tube gauge, you only need to set Scale Value to Transparent in Color, as shown in the following figure.

Gauge Scale Value Modifications

You can modify Target Value, which determines the maximum value of the scale, in the multi-pointer gauge and the test tube gauge, as shown in the following figure.

Gauge Style Setting

In FineBI6.0.15 and later versions, you can set Style for gauges to modify the size, style, tick mark thickness, and rounded corner status (enabled/disabled), as shown in the following figure.

You can create gauges with richer styles as needed.

In conclusion, the Gauge Chart is a critical tool in visual analytics, particularly effective in representing and monitoring real-time performance metrics against set goals. Its ability to provide instant visual cues on progress makes it essential for dashboard applications across various industries, enhancing decision-making processes by presenting clear, actionable insights at a glance.
