# XWUIChartStackedBar

A stacked bar chart: a fixed-type wrapper around `XWUIChart` that draws one bar per x-category and stacks each series as a colored segment within it, so the full bar height is the category total. Supply `{ series }` plus a `block` preset (1-4) and `size`. Use it for part-to-whole comparison across categories - segment sizes show each series' share of each bar.

## Basic Usage

This example renders two series (Series A and Series B) of six monthly values (Jan-Jun) as one bar per month with the two series stacked as segments that sum at each month, at medium size.

```example
file: examples/BasicUsage.ts
html: examples/BasicUsage.html
title: Basic Usage
description: Six monthly bars where Series A and Series B are stacked as colored segments, so each bar's total height is the sum of both series for that month.
```

## Quarterly Revenue by Region

Each quarter's bar stacks revenue from three regions so its height is total revenue.

```example
file: examples/RevenueByRegion.ts
html: examples/RevenueByRegion.html
title: Quarterly Revenue by Region
description: Six quarterly bars segmented into Americas, EMEA, and APAC, so each bar's height is total revenue and each segment is that region's share.
```

## Support Tickets by Priority

Weekly ticket volume stacked by severity to show both load and the priority mix.

```example
file: examples/TicketsByPriority.ts
html: examples/TicketsByPriority.html
title: Support Tickets by Priority
description: Weekly inbound tickets stacked as Critical, High, Medium, and Low segments, revealing total volume and how much of each week is high-severity work.
