Developer Note

Please don't be discouraged if you see that it has been "years" since an update, but rather think that Lavacharts has settled into a "stable" state and requires less tinkering from me. I would love to add new features, but my responsibilities leave little room for my projects. I am happy to field issues, answer questions, debug and help if needed. Lavacharts is not vaporware! 😄

Laravel

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

Laravel ~5.5

Thanks to the fantastic new Package Auto-Discovery feature added in 5.5, you're ready to go, no registration required 👍

Symfony

The package also includes a Bundle for Symfony to enable Lavacharts as a service that can be pulled from the Container.

Add Bundle

Add the bundle to the registerBundles method in the AppKernel, found at app/AppKernel.php:

<?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

Setting up your first chart.

Data

$data = $lava->DataTable();

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

// Random Data For Example
for ($a = 1; $a < 30; $a++) {
    $rowData = [
      "2017-4-$a", rand(800,1000), rand(800,1000)
    ];

    $data->addRow($rowData);
}

Arrays work for datatables as well...

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

Or you can use \Khill\Lavacharts\DataTables\DataFactory to create DataTables in another way

Chart Options

Customize your chart, with any options found in Google's documentation. Break objects down into arrays and pass to the chart.

$lava->LineChart('Stocks', $data, [
    'title' => 'Stock Market Trends',
    'animation' => [
        'startup' => true,
        'easing' => 'inAndOut'
    ],
    'colors' => ['blue', '#F4C1D8']
]);

Output ID

The chart will needs to be output into a div on the page, so an html ID for a div is needed. Here is where you want your chart <div id="stocks-div"></div>

• If no options for the chart are set, then the third parameter is the id of the output:

$lava->LineChart('Stocks', $data, 'stocks-div');

• If there are options set for the chart, then the id may be included in the options:

$lava->LineChart('Stocks', $data, [
    'elementId' => 'stocks-div'
    'title' => 'Stock Market Trends'
]);

• The 4th parameter will also work:

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

View

Pass the main Lavacharts instance to the view, because all of the defined charts are stored within, and render!

<?= $lava->render('LineChart', 'Stocks', 'stocks-div'); ?>

Or if you have multiple charts, you can condense theh view code withL

<?= $lava->renderAll(); ?>
