# Showcase

The flagship XWUIChartBlandAltman demo. It builds a full method-agreement plot from 18 paired readings (differences plus the bias line and the upper and lower 95% limits of agreement, all computed inline), then walks the four block presets, the sm/md/lg size scale, the axis and grid toggles, marker and stroke styling, and the value-label, interactive and loading states.

The reference lines are ordinary flat two-point series with a dashed per-series stroke, so nothing outside the component's own config and data contract is needed.
