The chart's data series, in declaration order.
OptionalsheetThe worksheet the chart is anchored to, when the relationship graph resolves it.
OptionaltitleThe chart's title, when it declares one.
OptionaltotalThe chart's true series count, present ONLY when extraction retained fewer series than the chart actually declares — so an omitted-series count is computed against what the chart HAS, not against what survived extraction's own cap.
One chart's cached content. Cached values are what the chart last rendered; formulas are not evaluated.
