Behavior

• Each binding (or row) is a slice, named in the legend by the binding's Label, or after the binding (value, value1…) when it has none.
• Zero, negative and non-numeric values are left out. If every value is zero the widget shows "Add bindings for pie slices" (or "No data" for a query).
• Slices use the same palette as the bar chart: twelve distinct colors, then generated ones, so slices never repeat a color.
