Multilevel Selection
The Multi-Level Selection feature in Play Axis allows filtering through all unique data point combinations when a multi-level hierarchy (more than one category) is added to the visual.
How to Configure
Add a multi-level hierarchy (e.g., Category > Subcategory > Product).
Enable Play Axis to filter through individual data points.
Toggle Multi-Level Selection to cycle through unique combinations instead of individual categories.
How It Works
Default Play Axis Behavior:
Cycles through top-level categories one by one, replacing the previous selection.
Example: Year - 2023 → 2024 → 2025 (only one category visible at a time).
With Multi-Level Selection Enabled:
Filters cycle through all unique combinations in the hierarchy instead of just categories.
Example:
Electronics > Mobile Phones > iPhone
Electronics > Mobile Phones > Samsung Galaxy
Apparel > Footwear > Sneakers
Apparel > Footwear > Sandals
Category selection and Cumulative Selection are disabled when this feature is enabled.
Filtering is done based on the unique combinations of values across those levels, rather than treating each level independently.
For example, if the hierarchy includes Year and Month, the Play Axis will filter in the sequence of unique Year-Month pairs, such as: 2022 - August → 2022 - September → ... → 2022 - December → 2023 - January → 2023 - February, and so on.
Category selection and Cumulative Selection are disabled when this feature is enabled.
This ensures that the filtering follows the actual chronological order of available data points, allowing for smooth time-based storytelling across multiple levels of a category.
Cumulative Selection
It allows users to apply filters incrementally rather than replacing them. With each new value, the filter builds upon the previous one, preserving earlier selections. In Multi-Level Selection, this means that all unique data point combinations are added one by one—creating a cumulative view that reveals how the trend evolves across different levels of the hierarchy.
Example:
In the video below, a Date Hierarchy consisting of Year and Month is added to the category section. Both Multi-Level Selection and Cumulative Selection are enabled in the Play Axis format pane. As a result, the data builds up incrementally—starting with July 2022, then adding August 2022 to show a progressive trend
