Highlight

Pulls one or more slices out of the crowd, selected by a regular expression rather than by hand — so the emphasis follows the data instead of a position on screen.

Property	Description	Default
Highlight slices	Master toggle	Off
Pattern (regex)	Case-insensitive regular expression	(empty)
Match on	Categories or Series	Categories
Match status	Read-only: how many slices matched, or why none did	—
Highlight mode	See below	Explode

The pattern carries the fx button, so a measure or a rule can compute which slices to emphasise — for example the top performer of the current filter context.

Highlight modes

Mode	Effect	Related settings
Explode	The matching slices slide outward along their own bisector	Explode Offset (px)
Outline	The matching slices get a thicker, colored border	Outline Color, Outline Width
Dim the others	Every non-matching slice drops to a lower opacity	Opacity of the others
Explode + outline	Both of the first two	All of the above

Only the settings that apply to the selected mode are shown in the pane.

Matching

• Categories matches the category label of each slice, so the same slice is emphasised on every chart — useful to follow one product across a grid of small multiples.
• Series matches the legend value, so a whole chart or a whole ring is emphasised.

The regex is case-insensitive. Other|Misc matches either word; ^Total$ matches the exact label. An invalid expression is reported in Match status and no slice is emphasised.

Interaction with cross-filtering

Clicking a slice cross-filters the report and dims the slices outside the selection. While a selection is active it owns the opacity of the chart; Dim the others takes over again as soon as the selection is cleared. Explode and outline are unaffected by selection.
