Gauges allow you to display the difference between the actual and target values of a particular parameter. This difference is called delta.
Delta is shown with a delta indicator (indicating whether the actual value is less than or greater than the target value) and delta values (representing this difference as an absolute value or a variation).
After you add the data item containing actual data, you can add the second data item (optional) that contains target data. To customise settings that relate to the calculation and display of deltas, open the Delta Options section of the data item menu.
Use it to define the conditions for displaying delta indication, specify which delta values should be displayed, and introduce the comparison tolerance.The following options are available.
| Option | Description |
|---|---|
| Value Type | Specifies which values should be displayed as the main delta value. Additional delta values are selected automatically. |
| Result Indication | Specifies the condition for displaying delta indication. |
| Threshold Type | Specifies the comparison tolerance in percentage values or in absolute values. |
| Threshold Value | Specifies the comparison tolerance value. |
By default, the Gauge dashboard item automatically determines the range of the gauge scales based on the values they display.
You can override this behaviour and specify maximum and minimum values on the scale. After you add the data item, open the Scale Options section of the data item menu to customise the gauge scale.
Then, set the minimum/maximum value mode to Custom and specify this value in the corresponding field. The image below shows a gauge with a minimum value of 1B and maximum 5B.
The Gauge dashboard item allows you to specify the number of columns or rows by which gauges are arranged. For example, the following image shows gauges arranged into 3 columns.
To control how gauges are arranged, use the Layout section in the Gauge's Options menu.
The following modes are available.
| Arrangement Mode | Description |
|---|---|
| Auto | Automatically resizes gauges to fit within the dashboard item. |
| Fixed Rows | Allows you to arrange gauges in a specific number of rows. |
| Fixed Columns | Allows you to specify the number of columns in which gauges are arranged. |
To specify the number of rows/columns, use the Line Count field.
The Gauge dashboard item allows you to select the gauge style.
The following types are available.
- Full Circular
- Half-Circular
- Left-Quarter Circular
- Right-Quarter Circular
- Three-Fourths Circular
- Linear Horizontal
- Linear Vertical
To select the gauge style, use the style icons in the Gauge Options menu.
