Data Splits
Data Splits let you segment your analysis results by one or two supporting variables — for example, breaking sentiment results out by region, or showing top terms separately for each customer type. Instead of one combined view, you get a separate chart series for each combination of values.
Configuring Data Splits
Section titled “Configuring Data Splits”- In the Workbench toolbar, click Data Splits.
- The Data Splits panel opens, showing all available supporting variables from your project.
- Select up to two variables to split by.
- Click Apply. The Workbench generates result sets for each combination of the selected variable values.
All analysis types in the project use the same Data Splits configuration. Changes apply across all charts.
Choosing your split variables
Section titled “Choosing your split variables”Any categorical supporting variable you added during project setup is available as a split variable. Numeric variables that have been coded into categories are also available.
Using date variables
Section titled “Using date variables”If you select a date or time variable, additional options appear:
| Setting | Description |
|---|---|
| Aggregation type | How to group dates — options include Calendar Year, Financial Year (with different start month options), Quarter, Month, Week, Day, and Hour |
| Date format | How dates are displayed in the chart legend and axis labels |
Choosing the right aggregation level depends on your data volume and the time span covered. Monthly aggregation is a good default for most projects. Financial year options are available if your organisation uses a non-calendar financial year.
Selecting individual values
Section titled “Selecting individual values”By default, all values for a selected variable are included. To focus on a subset:
- Expand the variable in the Data Splits panel.
- Deselect any values you do not want included.
- Use Select all remaining to quickly reselect all values if you change your mind.
Removing a split
Section titled “Removing a split”To remove a split variable, click the × next to the variable name in the Data Splits panel, then click Apply. Analysis results return to the combined (unsplit) view.
Frequently asked questions
Section titled “Frequently asked questions”Can I use a text variable as a split?
No. Only categorical and date supporting variables can be used as split variables. Text variables are the source of analysis, not a basis for segmentation.
Why is my combination count higher than expected?
The combination count is the product of the number of selected values from each variable. For example, 5 regions × 4 customer types = 20 combinations — exactly at the limit. Deselect values you don’t need to bring the count down.
Do Data Splits affect the Text Auto Report?
Yes. If a Text Auto Report is linked to your project, it will reflect the Data Splits configuration and display segmented results accordingly.
