Gauge Widget
This type of widget belongs to the Dashboards category in the widget library. It enables you to place, for a given dimension element, an observed value on a semicircular gauge using a pointer. Analysis is easier using a quantitative scale with thresholds that define the display color of segments of the gauge, e.g. red, yellow or green.
Notes
see General remarks on widgets
- The data source must contain one Dimension column and one Measure: Observed value column.
- The gauge can only process one dimension element. Besides the row headers, the data source must contain only the row related to this dimension element.
- The legend of the chart corresponds to the dimension element.
Best Practice
- You should use the Gauge widget to highlight a value as compared with thresholds that display different segments graphically using customizable colors.
- To highlight a value as compared with a target figure using a chart, you should use the Bullet Chart widget.
Example
You want to view the figure (pointer) for the number of late incidents (measure) in a quantitative scale divided into 3 segments:
| Data source | Gauge widget (gauge with values from 0 to 50)
with a quantitative scale consisting of 2 thresholds (3 intervals) |

List of properties
Content
DataSource
Data Source: External data source associated with the widget.
- The drop-down list displays all of the data sources available in the app.
- To modify the data source or to view its contents, you should click
. The 
button below the Preview property shows the number of rows (max. 15) and columns extracted. - To define a new data source, click
Add Data Source in the Objects pane.
DataTransformer
Data Transformer: Used to define the structure and scope of the data source, apply statistical aggregate functions and modify the order of the measures displayed.
- Click Setup / Preview Data below the Data Transformer property to open the dedicated window. See the description.
ThresholdsStatus
Threshold Status: Used to define 1 to 4 quantitative thresholds using a scale of values (2 to 5 intervals). Each new threshold will be displayed in a different color.
Thresholds define the display color of segments of the gauge.
See Example and Procedure.DefineThresholds
| Reduce display mode | Expand display mode |
|---|---|
|
You can define three color segments with two thresholds.
|
You can define five color segments with four thresholds.
|
Min Value: Start value of the gauge. By default, zero.
Max Value: End value of the gauge. By default, the observed value in the data source.
Data
SortByValueDescending
Sort By Value Descending: Used to sort dimension elements in descending order (if the box is checked, from highest to lowest value) or in the order in which they are read in the data source (box is not checked). Note: The order applied is determined by the dimension elements of the first measure in the data source.
Click to see an example: Charts for incidents and requests per employee
The data source contains the Department dimension with three elements. 
| Box is checked | Box is not checked |
|---|---|
|
The dimension elements of each measure are sorted in descending order. |
The dimension elements of each measure are displayed according to the sort order of the data source. |
MaximumNumberOfData
Maximum Number Of Data: Used to indicate the maximum number of dimension elements to be loaded from the data source for each measure selected in the data source.
You should use this property to prevent loss of performance when data volume is large.
- The count is always performed from the first dimension element.
- When the number of dimension elements to be loaded is greater than the number of dimension elements in the data source, all of the data is loaded.
- To view the data source, click next to the Data source property, then click button below the Preview property which shows the number of measures and the number of dimension elements for each measure.
Click to see an example: Charts for incidents and requests per employee
The data source contains the Department dimension with three elements.
Maximum Number Of Data = 20 (default value)
Maximum Number Of Displayed Data = 20 (default value) |
Maximum Number Of Data = 2
Maximum Number Of Displayed Data = 20 (default value) |
Maximum Number Of Data = 20 (default value)
Maximum Number Of Displayed Data = 1 |
|---|---|---|
|
All dimension elements are loaded and displayed for each measure, i.e. the three departments. |
Only the first two dimension elements are loaded and displayed for each measure, i.e. the first two departments. |
All dimension elements are loaded but only the first element is displayed. This corresponds to the Sales department. The Others dimension element groups values from the Marketing and Administration departments. |
Chart
Title: Name of the chart displayed below the gauge. Note: If you do not specify this field, the name of the Dimension column will be used.
Width Scale (0.10 - 1.5): Tool used to modify the width of the gray inner semicircle and the threshold semicircle.
| Width = 0,2 | Width = 1,5 |
|---|---|
 |
 |
Show Background Color: Used to indicate if the gray inner semicircle should be displayed on the gauge (box is checked) or not (box is not checked). Note: Use the Shadow Scale property to modify the width.
| Box is checked | Box is not checked |
|---|---|
 |
 |
Show Shadow: Used to indicate if the shadow of the gray inner semicircle should be displayed on the gauge (box is checked) or not (box is not checked). Note: Use the Shadow Scale property to modify its width.
| Box is checked | Box is not checked |
|---|---|
 |
 |
Shadow Scale (0.8 - 1.5): Tool used to modify the width of the gray inner semicircle shadow.
Needle Stroke Color: Used to indicate if the outline of the pointer is displayed in a specific color (box is checked) or in black (box is not checked).
Needle Color: Used to indicate if the inside of the pointer is displayed in a specific color (box is checked) or in black (box is not checked).

Procedure: How to define thresholds
ProcedureDefineThresholds
Step 1: Specifying the number of thresholds
1. Click 
in the Thresholds Editor Properties > Ranges domain field to switch to the Reduce mode with three thresholds.
2. Click 
to switch to the Expand mode with five thresholds.
Step 2: Specifying the threshold values
1. Enter the value for the threshold of each segment in the Status Thresholds field.
2. Select the color of each segment.
- Move the cursor over the threshold color, click
and select the color you want from the Color Picker.
- You can also enter the hexadecimal code of the color directly in the color field.
3. (optional) Click [ ON ] in Thresholds Editor Properties > Symmetric colors if you want colors to be symmetrical based on the color of the central segment.
