Installing

In your project's main composer.json file, add this line to the requirements:

"khill/lavacharts": "~3.0"

Run Composer to install Lavacharts:

$ composer update

Framework Agnostic

If you are using Lavacharts with Silex, Lumen or your own Composer project, that's no problem! Just make sure to: require 'vendor/autoload.php'; within you project and create an instance of Lavacharts: $lava = new Khill\Lavacharts\Lavacharts;

Laravel

To integrate lavacharts into Laravel, a ServiceProvider has been included.

Laravel 5.x

Register Lavacharts in your app by adding this line to the end of the providers array in config/app.php:

<?php
// config/app.php

// ...
'providers' => [
    ...

    Khill\Lavacharts\Laravel\LavachartsServiceProvider::class,
],

The Lava:: alias will be registered automatically via the service provider.

Laravel 4.x

Register Lavacharts in your app by adding this line to the end of the providers array in app/config/app.php:

<?php
// app/config/app.php

// ...
'providers' => array(
    // ...

    "Khill\Lavacharts\Laravel\LavachartsServiceProvider",
),

The Lava:: alias will be registered automatically via the service provider.

Symfony 2.x

Also included is a Bundle for Symfony to create a service that can be pulled from the Container.

Add Bundle

Add the bundle to the AppKernel:

<?php
// app/AppKernel.php

// ...
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...

            new Khill\Lavacharts\Symfony\Bundle\LavachartsBundle(),
        );

        // ...
    }

    // ...
}

Import Config

Add the service definition to the app/config/config.yml file

imports:
  # ...
  - { resource: @LavachartsBundle/Resources/config/services.yml

Usage

The creation of charts is separated into two parts: First, within a route or controller, you define the chart, the data table, and the customization of the output.

Second, within a view, you use one line and the library will output all the necessary javascript code for you.

Basic Example

Here is an example of the simplest chart you can create: A line chart with one dataset and a title, no configuration.

Controller

    $stocksTable = $lava->DataTable();  // Lava::DataTable() if using Laravel

    $stocksTable->addDateColumn('Day of Month')
                ->addNumberColumn('Projected')
                ->addNumberColumn('Official');

    // Random Data For Example
    for ($a = 1; $a < 30; $a++)
    {
        $rowData = [
          "2014-8-$a", rand(800,1000), rand(800,1000)
        ];

        $stocksTable->addRow($rowData);
    }

Arrays work for datatables as well...

  $stocksTable->addColumns([
    ['date', 'Day of Month'],
    ['number', 'Projected'],
    ['number', 'Official']
  ]];

...and for setting chart options!

  $lava->LineChart('Stocks', $stocksTable, ['title' => 'Stock Market Trends']);

View

If you are using Laravel and the Blade templating engine, there are some nifty extensions thrown in for a cleaner view

@linechart('Stocks', 'stocks-div');
// Behind the scenes this just calls Lava::renderLineChart('Stocks', 'stocks-div')
// which is an alias for the render method, seen below

Or you can use the new render method, passing in the chart type, label, and element id.

echo Lava::render('LineChart', 'Stocks', 'stocks-div');

This is all assuming you already have a div in your page with the id "stocks-div": <div id="stocks-div"></div>

If you don't have a div ready to accept the charts, add one more parameter to @linechart() or render() and it will be created for you.

Add true to for the library to create a plain div, or an array with keys width & height

Example:

@linechart('Stocks', 'stocks-div', true)
// Or
echo Lava::render('LineChart', 'Stocks', 'stocks-div', ['width'=>1024, 'height'=>768]);
