# XWUIChartLine

A line chart block backed by `XWUIChart` that connects data points into continuous lines, the default choice for trends and time series. 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 monthly series - `Series A` (30→64) and `Series B` (22→52) across Jan-Jun - drawn as trend lines.

```

## Multi-Series Trends

Three regional revenue series (Americas, EMEA, APAC) drawn together with the legend enabled so each color-cycled trend line stays identifiable.

title: Multi-Series Trends

```

## Smooth High-Resolution Trend

There is no curve/spline option, so a smooth look comes from sampling one series at 180 densely-spaced points (markers off) - never faked interpolation.

```example
file: examples/Smoothed.ts
html: examples/Smoothed.html
title: Smooth High-Resolution Trend
description: 180 dense points read as one continuous smooth curve.
```

## Points & Tooltips

Filled point markers plus `interactive: true` give a hover crosshair and a per-point tooltip, with values suffixed by a `" ms"` unit.

```example

```

## Dense Daily Time Series

A full year of daily readings (365 points) with month tick labels via a custom `xAxisLabelFormatter` and a thousands-separated tooltip `valueFormatter`.

```example
file: examples/DenseTimeSeries.ts
html: examples/DenseTimeSeries.html
title: Dense Daily Time Series
description: 365 daily points sampled down to twelve month ticks.
