Keep numbers numeric. Two text coordinates are not a basic chart point. A numeric X/Y point needs a non-empty label, and duplicate coordinates within one named list are rejected. Bar and slice charts require a category; numeric X/Y uses line or area.
Use more than one named list to compare groups. Percentage stacks need a positive total at every coordinate. Stacks and slices reject more than 256 displayed points rather than changing the meaning of totals. Intermediate and advanced examples are proposed contracts.
