Tag Cloud Widget
This widget belongs to the Dashboards category in the widget library. For a given measure, it provides a graphic display of the text values of dimension elements in a tag cloud. The importance of a keyword in the tag cloud is determined by its frequency, i.e. the number of occurrences in the data source. This is highlighted accordingly by its font size and color.
You can define the visual aspect of the tag cloud using different properties, e.g. text color, rotation, font, etc.
Examples
Data in the CSV file
- Dimension = Location
- Measure = Number of equipment
- Elements displayed: Words corresponding to locations, graphically formatted based on the importance of the number of equipment

Notes
- The Tag Cloud widget requires a data source that will retrieve a report, view or CSV file with two columns (grouping levels), i.e. Label and Value.
Note: If the data source contains several columns, you should use the Data Transformer to select the two columns you want.- Column 1: Dimension
- Column 2: Values of the measure elements to be displayed
- The font size of each keyword is proportionate to the value of the dimension element in the data source.
- Each keyword is displayed in the color associated with its value in the legend axis.
- In execute mode:
- Tooltips appear when you move the cursor over each keyword.
- When you click a value in the legend axis, all keywords corresponding to this value will appear in black.
Caution
- The tag cloud displays text data. If the keywords to be displayed contain numbers, they will be interpreted as text data and not as Integer or Float data.
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.
EnableDrilldown
Enable Drilldown (Note: Only for an EasyVista data source data source using a view with grouping levels): Used to indicate if data is aggregated (box is checked - the drill-down functionality is enabled) or not (box is not checked).
example Breadcrumbs widget: Breakdown of equipment by location.
- If you want the widget to display the breakdown in a grouping level, you should not check this box.
- Add a Breadcrumb widget to facilitate navigation within grouping levels.
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.
example You want to display the chart 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. |
FirstRowContainsDimensionElements
First Row Contains Dimension Elements: Used to specify the structure of the data source by indicating if dimension elements are found in the first column (box is not checked: standard data source structure) or in the first row (box is checked). Note: This property does not affect the behavior of the Data Transformer.
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.
example You want to display the chart for incidents and requests per employee
The data source contains the Department dimension with three elements.
|
|
|
|---|---|---|
|
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. |
MaximumNumberOfDisplayedData
Maximum Number Of Displayed Data: Used to indicate the maximum number of dimension elements to be displayed for each measure selected in the data source. This improves chart readability.
example You want to display the chart for incidents and requests per employee. See the Maximum Number Of Data field.
- The count is always performed from the first dimension element.
- When the number of dimension elements to be displayed is less than the number of dimension elements to be loaded, the Others dimension element will automatically be added to the chart. It will aggregate all of the values from non-displayed dimension elements.
Charts
Position: Keyword display type.
- Spiral: Keywords are displayed in a spiral.
- Rectangle: Keywords are displayed in a rectangle.

Color Range: Used to indicate if the legend axis should be displayed below the chart (box is checked) or not (box is not checked).
- The color of each segment in the axis is determined by the theme.
Series Angle: Series of values indicating the rotation angle of keywords.
- You can specify a value between -180 to 180.
- If you enter 0, this means that keywords will be displayed horizontally with no rotation.
- If you enter -180 or 180, this means that keywords will be displayed horizontally upside down, i.e. with a rotation of 180°.
- You can enter several values. They will be assigned randomly to the keywords.
Text Spacing: Space, in pixels, between keywords.
| Space: 0 | Space: 10 |
