SDM Smart PieChart

The SDM Smart Pie Chart renders a composition as a pie, a donut, or a half-circle gauge. Each slice is a category; each legend value adds a whole chart, drawn either as a small multiple or as a concentric ring.

Key features:

• Three shapes: full circle, top half circle and bottom half circle. A half circle is not a cropped pie — the whole series is laid out over 180°, so a half donut reads as a gauge without a dummy remainder slice
• Pie or donut: an adjustable inner radius unlocks the center label and the concentric-rings layout
• Small multiples: one chart per legend value in a grid, with a cap per row and a centred partial last row
• Concentric rings: several series nested in a single donut, with configurable gap and ring order
• Regex highlighting: emphasise slices by pattern rather than by hand — explode, outline, dim the others, or explode and outline together
• Target line: a radial mark at the target angle, as a value or a share, with a per-series rule so every small multiple gets its own goal
• Center label: the total or any caption in the hole of the donut, with an optional sub-title
• Significance testing: every series compared to a reference series picked by regex, on shares or means, shown as an icon, a slice outline or a label background
• Data-driven colours and logos: colour the slices or the charts, and feed logos to the legend, the slices and the series titles
• Cross-filtering and rich tooltips: click or Ctrl+click a slice to filter other visuals; category, value, share, base and custom measures on hover

Available in 10 languages and compatible with Microsoft Fabric. Built for survey research, brand tracking and executive dashboards, where a composition has to be compared across groups rather than just displayed.
