Drilling through hierarchical data in a story

In stories with a board layout, drilling through hierarchical data has the same capabilities as drilling in the Visualization room. If the story contains more than one visualization with the same hierarchical dimension, all visualizations in the story are updated. Input controls and filters applied to the story are maintained during the drill and drill back operations.
The drill operation consists of:
  • applying a filter

  • redrawing the visualization at the new level of the hierarchy
When you drill through one visualization in a story, the filter is applied to all visualizations that contain the same hierarchical dimension. The selected visualization, and any other instances of that visualization in the story, are redrawn at the new level in the hierarchy. Other visualizations remain drawn at the previous level.
The updates from drilling are applied to the visualization in the Compose room.
Note

Drilling is only available in stories with a board layout.

  1. Select an area in a visualization to drill through.
  2. In the tooltip that appears, select the drill down or drill up icon.

    The filter is applied to every visualization in the story, and the selected visualization is re-drawn at the new level in the hierarchy.

  3. To step back through the drill operation, select the drill back icon.

    The filter created by the drill action is removed from all visualizations in the story. The selected visualization is re-drawn at the previous level. Any filters or input controls applied by hand are maintained. Note that the drill back history is reset when you switch to the Compose room.
