Word Cloud Chart
A word cloud chart displays textual values in relation to each other, where different values can have different weights and thus a different size. This concept is also known as a tag cloud.
Data Requirements
The word cloud chart is available if the query results contain a textual column and optionally a numerical column whose values can be interpreted as the "weight" of the textual value. For example, a query result such as
| value | weight |
|---|---|
| a | 1 |
| b | 2 |
| c | 3 |
| d | 4 |
| e | 5 |
| f | 6 |
produces a word cloud chart that looks as follows (with the default configuration)
Interactive Features
Tooltips
When hovering the cursor over a term, a tooltip is shown with the text and weight of the term and, if present, information from additional result columns.
Configuration
The following options are available for the general word cloud chart configuration:
- Tooltips: Whether tooltips are enabled.
Columns
The column configuration determines which result column is used for the "words" and which is used for the "values" (i.e. weights). The values of any additional columns are only displayed as part of tooltips (if enabled).
Additional Options
The following additional options are available in the word cloud chart configuration:
- Max number of words: The maximum number of words (1-100) that are
included in the chart. Only the words with the
nlargest values ("weights") will be shown.
Drill-Down
A drill-down can be configured for the word cloud chart, so that when clicking on a word a filter value is applied on the same or a different dashboard.
Use Navigate to to select the target dashboard of the drill-down action.
If the target dashboard is not the same dashboard that the word cloud chart is on,
the UI navigates to the chosen dashboard.
In the Apply filters section, select one or more filters from the target
dashboard and for each a column whose value should be applied to it
when the user performs the drill-down.
