# XWUIChartCombo

A combo chart: a fixed-type wrapper around `XWUIChart` that overlays more than one
series type (for example columns plus a line) on shared axes so two measures can be
read against each other in a single frame. Pass `series` of `{ x, y }` data plus a
`block` preset (1-4) and `size` (`sm` / `md` / `lg`); the shared block
config also exposes legend, grid, axis, data-label, and tooltip-formatter toggles.
Use it to relate two measures that share an x-axis but read better in different forms.

## Basic Usage

Two monthly `{ x, y }` series fed to the combo renderer at the md size preset,
overlaying the series types on shared axes.
