# XWUIChartTimeSeriesArea

A time-series area chart: a fixed-type wrapper around `XWUIChart` that plots values over a time axis and fills the area beneath each line, emphasizing magnitude and accumulation across the period. Supply `{ series }` of `{ x, y }` points plus a `block` preset (1-4) and `size`. Use it for trends over time where the filled volume under the curve reinforces the sense of total.

## Basic Usage

This example plots the two series, Series A and Series B, over the six-month time axis (Jan through Jun) and fills the area beneath each line, so the rising monthly values read as growing filled volume at medium size.

```

## Daily Active Users

Plots a month of daily active users as a single filled area with a crosshair and thinned x-axis labels, so the steady upward climb through June reads as growing volume under the curve.

```example

html: examples/DailyActiveUsers.html
title: Daily Active Users
description: A month of DAU as a filled area with crosshair, interactivity, and a capped x-axis label count.
```

## Reservoir Level Over a Year

Overlays a year of monthly capacity for two reservoir basins as filled areas, making the shared summer drawdown and autumn refill visible as the volumes shrink and recover together.

description: Two reservoir-capacity series as overlaid filled areas with x-axis labels, crosshair, and a percent unit.
