Show Items with No Data
Overview
The Show Items with No Data feature in Datafor allows report components such as tables and charts to display dimension values even if they do not have corresponding data. This ensures completeness in data visualization and prevents missing key insights.
1. Use Cases
This feature is useful in the following scenarios:
- Time Series Analysis: Ensures all dates appear on the timeline, even if there is no data for certain days.
- Categorical Analysis: Displays all product categories, customers, or regions, even if they have no recorded data.
- Data Quality Monitoring: Helps identify missing data for certain categories, facilitating further investigation.
2. How to Enable "Show Items with No Data"
Select a chart or table component.
In the Fields panel, locate the dimension field you want to display even when it has no data (e.g., product category, date).
Open the field’s menu and select "Show Items with No Data".
The report will now display all values for the selected field, even those without data.
