# XWUIChartRollingAverage

A rolling-average chart: a fixed-type wrapper around `XWUIChart` that smooths a time series
with a moving average so short-term noise drops away and the underlying trend stands out.
Pass your data as `series` of `{ x, y }` values plus an optional `block` preset (1-4) and
`size` (`sm` / `md` / `lg`); the shared block config also forwards legend, grid,
axis, data-label, and tooltip toggles. Use it when the trend matters more than the jitter.

## Basic Usage

Two named series of monthly values rendered as smoothed rolling-average lines at the medium
size preset.
