# XWUIChartECDF

An ECDF (empirical cumulative distribution function) chart variant backed by `XWUIChart` that steps from 0 to 1 as it accumulates observations, letting you read percentiles and compare whole distributions directly. Provide named `series` of `{ x, y }` points and choose a `block` (1-4) and `size` preset.

## Basic Usage

Two named monthly series (Series A and Series B), each spanning Jan through Jun, drawn as cumulative step curves.

## Response Time Distribution

A single latency distribution where the curve rises to 100% and a p95 line marks the request-latency target.
