# XWUIChartMixed

A mixed (combo) chart: a fixed-type wrapper around `XWUIChart` (resolving to the `combo`
renderer) that overlays more than one mark type - typically bars and a line - on shared axes,
so series measured differently can be compared in one frame. Construct it with
`(container, data, conf_comp)` where data is `{ series, title? }`, then pick a `size` preset
and a `block` (1-4) styling variant. Use it when one series reads best as columns and another
as a trend line (e.g. revenue bars with a margin line).

## Basic Usage

Two named series of monthly values rendered as a combined bar-and-line chart at the medium
size preset.

## Revenue and Gross Margin

A revenue series paired with a dashed gross-margin series so a volume metric and a rate metric share one frame.

html: examples/RevenueAndMargin.html
title: Revenue and Gross Margin
description: Quarterly revenue with a dashed margin line as a combination chart.
```

## Traffic and Conversion Rate

Daily sessions overlaid with a dotted conversion-rate line to separate volume from rate.

```example
file: examples/TrafficAndConversion.ts
html: examples/TrafficAndConversion.html
title: Traffic and Conversion Rate
description: Site sessions and conversion percentage drawn with distinct line styles.
