# XWUIChartZScore

A z-score chart backed by `XWUIChart` that plots values as standard deviations from the mean, making outliers and relative position easy to read on a normalised scale. 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 series - `Series A` (30→64) and `Series B` (22→52) across Jan-Jun - expressed as z-scores.
