Chart Blocks

Open source

Chart compositions on the chart-card shell: a KPI metric with a headline figure, a dual-axis column/line combo, a waterfall bridge and a grid of liquid gauges. One chart in a card is chart-card plus a chart example. Comparison instead frames a two-series bar chart in a tray, with a range select swapping the bundled dataset client-side.

# Brok UI block: Chart Waterfall (`chart-waterfall`)

A chart card bridging a running total across rising and falling steps to a net figure, turning a list of deltas into floating range bars.

Brok UI is a Laravel Blade registry. `ui:add` copies this block into the app as plain Blade the app owns; it composes installed `<brok:*>` primitives and semantic design tokens.

## Install

```bash
php artisan ui:add blocks/chart-waterfall
```

## Render it

```blade
<x-blocks.chart-waterfall />
```

## Props

- `heading` (string, default `Cash flow bridge`) — Card title.
- `subheading` (string, default `This quarter ($k)`) — Supporting description.
- `trend` (string|null, default `+40k`) — Delta badge.
- `steps` (array|null, default `null`) — Rows of {label, delta}; a null delta marks a total bar spanning zero to the running cumulative.
- `height` (int, default `320`) — Chart height in pixels.

## Use when

- A total has to be explained as a sequence of gains and losses.
- A cash-flow, budget-variance or headcount bridge is shown from opening to closing balance.

## Avoid when

- The steps do not accumulate; a bar chart is clearer.
- The parts are shares of one whole; use a pie or treemap.

## Rules

- Render the installed block with `<x-blocks.chart-waterfall />` and pass data through its props; edit the copied file only for structural changes.
- Keep the semantic design tokens (`bg-background`, `text-muted-foreground`); never swap in raw colour utilities.
- Keep the `data-slot` attributes and the logical (start/end) spacing so the markup still mirrors under `dir="rtl"`.

Guidance

Use when

A total has to be explained as a sequence of gains and losses.
A cash-flow, budget-variance or headcount bridge is shown from opening to closing balance.

Avoid when

The steps do not accumulate; a bar chart is clearer.
The parts are shares of one whole; use a pie or treemap.

Anti-patterns

Do not replace semantic props with conflicting utility classes.
Do not remove labels, focus styles, or state attributes.

Anatomy: chart card trend badge floating range bars total bar

Usage

Render the block as a component, passing data where useful:

resources/views/welcome.blade.php Blade

<x-blocks.chart-waterfall />

Built from primitives

Composes <brok:*> Semantic tokens Re-themeable RTL-ready

This block composes installed <brok:*> primitives and semantic design tokens only — it does not reimplement any primitive. Re-theme it (light, dark, admin, customer) by editing CSS variables; flip the preview to RTL to confirm it mirrors.
