Charts

Description

Charts is Laravel Enso's backend chart payload builder for the @enso-ui/charts frontend package.

It provides fluent factories for the chart types used across Enso dashboards and reporting screens, then returns normalized arrays that can be serialized directly to the frontend. The package also centralizes default chart colors, plugin defaults, datalabel handling, and axis configuration so host applications can generate consistent Chart.js payloads without hand-crafting dataset structures.

Installation

This package comes pre-installed in Laravel Enso applications that render chart widgets or dashboard analytics.

For standalone installation inside an Enso-based application:

composer require laravel-enso/charts

The package auto-registers its service provider and merges the enso.charts configuration namespace.

If you need to publish the configuration file:

php artisan vendor:publish --tag=charts-config

or:

php artisan vendor:publish --tag=enso-config

Features

• Provides dedicated factories for:
  • bar charts
  • line charts
  • bubble charts
  • radar charts
  • pie charts
  • doughnut charts
  • polar area charts
• Returns Chart.js-ready payloads through a single get() call.
• Supports fluent chart metadata such as:
  • title
  • aspect ratio
  • plugin configuration
  • per-option overrides
• Supports per-axis configuration for Cartesian charts.
• Supports per-dataset configuration overrides by dataset label.
• Supports custom palettes through colorsConfig().
• Supports chart datalabel configuration through datalabels().

• Supports short-number formatting hints for the frontend.
• Ships default Enso chart colors and plugin defaults in config/enso/charts.php.

Usage

Bar chart

use LaravelEnso\Charts\Factories\Bar;

$chart = (new Bar())
    ->title('Quarterly revenue')
    ->labels(['Q1', 'Q2', 'Q3', 'Q4'])
    ->datasets([
        'Revenue' => [12000, 18000, 15000, 22000],
        'Forecast' => [10000, 16000, 17000, 21000],
    ])
    ->gridlines()
    ->shortNumbers()
    ->get();

Line chart

use LaravelEnso\Charts\Factories\Line;

$chart = (new Line())
    ->title('Users by month')
    ->labels(['Jan', 'Feb', 'Mar'])
    ->datasets([
        'Users' => [20, 40, 35],
    ])
    ->fill()
    ->get();

Bubble chart

use LaravelEnso\Charts\Factories\Bubble;

$chart = (new Bubble())
    ->title('Portfolio risk')
    ->labels(['Low risk', 'High risk'])
    ->datasets([
        [
            [12, 4, 10],
            [18, 8, 25],
        ],
        [
            [9, 6, 15],
            [15, 12, 20],
        ],
    ])
    ->get();

API

Factories

• LaravelEnso\Charts\Factories\Bar Adds horizontal() and stackedScales() helpers for bar datasets.
• LaravelEnso\Charts\Factories\Line Adds fill() for filled line charts.
• LaravelEnso\Charts\Factories\Bubble Maps [x, y, radius] tuples into bubble datasets and can auto-scale radius values.
• LaravelEnso\Charts\Factories\Radar Builds radar chart datasets.
• LaravelEnso\Charts\Factories\Pie Builds pie chart payloads.
• LaravelEnso\Charts\Factories\Doughnut Builds doughnut chart payloads.
• LaravelEnso\Charts\Factories\Polar Builds polar area chart payloads.

Shared fluent methods

All chart factories inherit these methods from LaravelEnso\Charts\Factories\Chart:

• title(string $title)
• labels(array $labels)
• datasets(array $datasets)
• ratio(float $ratio)
• option(string $option, mixed $value)
• plugin(string $plugin, mixed $config)
• shortNumbers(int $precision = 2)
• gridlines()
• autoYMin()
• datalabels(array $config)
• colorsConfig(array $colors)
• datasetConfig(string $dataset, array $config)
• xAxisConfig(array $config, ?string $dataset = 'x')
• yAxisConfig(array $config, ?string $dataset = 'y')
• get()

Payload shape

The factories return arrays with this top-level structure:

• type
• title
• data
• options

For Cartesian charts, data contains:

• labels
• datasets

For bubble charts, data contains:

• datasets

Each dataset is normalized for the target chart type and enriched with default Enso colors plus datalabel configuration.

Configuration

Config file:

• config/enso/charts.php

Current package options:

• fillBackgroundOpacity Opacity used when converting a hex color into an RGBA fill color.
• options Default Chart.js options merged into each factory response.
• colors Default Enso chart palette used when no custom colors are supplied.
