# XWUIChartDualAxisCombo

A dual-axis combo chart variant backed by `XWUIChart` that overlays two series against independent left and right axes, the right tool when the quantities share a category axis but differ in scale or unit. Provide named `series` of `{ x, y }` points and choose a `block` (1-4) and `size` preset.

## Basic Usage

Two named monthly series (Series A and Series B), each spanning Jan through Jun, plotted across paired axes.
