# XWUIChartProbabilityDistribution

`XWUIChartProbabilityDistribution` is a thin wrapper around `XWUIChart` that fixes the chart `type` to `'probabilityDistribution'`, so you get a distribution/density-style plot without configuring the base chart yourself. Feed it a `{ series }` data object - each series renders as its own distribution curve - and reach for it when you want to compare how values are spread across a range (likelihood by bucket) rather than tracking a single running total. Layout is driven by the `block` (1-4, clamped) and `size` (`sm` / `md` / `lg`) config.

## Basic Usage

This example plots two monthly series (Series A and Series B, Jan-Jun) at the default `md` size, letting you eyeball how the two distributions sit against each other.

## Server Latency Distribution

A single frequency curve of API requests bucketed by response latency, with a red line marking the volume at the 200ms SLA budget.

title: Server Latency Distribution
description: Request counts across latency buckets (10ms-500ms) with a lineY annotation at the 200ms SLA budget, shown large with grid values and filled points.
```

## A/B Test Conversion Spread

Two overlaid conversion-rate distributions from an A/B test, showing how the variant shifts the curve to the right of the control.
