Chart families
What each family accepts and the parts it lets you replace.
- Vertical barsGrouped and stacked bars on a shared zero baseline, with lines over the stack.
BarChartPlot barsstack - Stacked areaSum and percent stacks with original values in every readout.
ChartPlot stackAreaLine - Combo chartsBars and lines on one plot, with an optional secondary scale.

Current limits
One active plot belongs to a Cartesian chart root. Line and Area marks draw long series from each pixel column's first, last, lowest and highest observation (decimate, on by default); hover, values, range summaries and exports still read every observation, and other Cartesian marks use the full series. Decimation selects original observations without averaging them. Card summaries and statistical families calculate the aggregates described on their own pages. Radial charts do not expose Cartesian range operations.
