# XWUIChartHalfLife

A half-life chart variant backed by `XWUIChart` that traces exponential decay over time, the shape for showing how a quantity falls toward zero and how long each halving takes. It inherits the shared chart-block contract, so provide named `series` of `{ x, y }` points and choose a `block` (1-4) and `size` preset with no per-variant configuration overhead.

## Basic Usage

Two named monthly series (Series A and Series B), each spanning Jan through Jun, plotted as decay curves.

## Radioisotope Decay

Two medical isotopes decaying from full activity, contrasting iodine-131's slow fall with the rapid technetium-99m.

## Drug Plasma Clearance

A drug's plasma concentration falling over 24 hours after one dose, each halving marking the elimination half-life.
