Set the first filter for a frame to be added as the z-axis (depth) of charts and column labels of pivots. The feature is available only if Allow first filter to be added to Z/Top Axis is set for the frame in Step 4: Associate Frames with Charts, Pivots, or Tables.
The number of filter values set must be lower than the specified threshold, to be visible in the embedded chart or pivot. The threshold is set in Step 7: Configure Properties.
If set filter values exceed the specified threshold, a default Auto Z column is displayed to signify the presence of a z- or top (column) axis. See Using Auto Z.
If Auto Z is enabled, do not use Quick Slice to add the first filter column on the z-axis (depth) of that frame.
