# XWUIChartMultipleLine

A multiple-line chart backed by `XWUIChart` that draws several named lines on one set of axes for direct trend comparison, with no per-variant configuration overhead. Provide named `series` of `{ x, y }` points and pick a `block` (1-4) variant plus a `size` preset; legend and grid auto-toggle per block unless overridden.

## Basic Usage

Two named monthly series - `Series A` (30→64) and `Series B` (22→52) across Jan-Jun - drawn as multiple lines.
