Mixed · Trend and snapshot

Columns and a line share axes; a separate pie panel shows the final category.

Use a shared Y scale for comparable units. For different measures, declare secondaryY and assign series explicitly; independent values keep their own units and domain.

Use type: mixed with type: line, area or column on each scalar series. Supplied arearange/areasplinerange bounds can instead accompany original lines on one common Y scale. X is categorical; primary Y and optional secondaryY are linear. Series yAxis selects primary or secondary. One original series per scale is required when the secondary axis exists.

Configure shared detail, independent axis titles/visibility/units, markers, colours, references and viewport. All columns share adjacent slots. Y/XY zoom uses primary source units and links secondary physical fractions. Column series reject curve and gaps; mixed stacking and logarithmic scales are unavailable.
