PHP project to generate clean-looking SVG price charts

![Dash 24h price in BTC from Poloniex](http://cryptohistory.org/charts/dark/dash-btc/7d/svg)  
7d of Dash price in Bitcoin from Poloniex.com

## Requirements

* PHP >=5.3.0

## Installation
### Using Composer

To install using Composer, you will have to install Composer first.

`curl -s https://getcomposer.org/installer | php`

Create a composer.json file in your project root.

```json
{
  "require": {
    "seigler/neat-charts": "@dev"
  }
}
```

Tell Composer to install the required dependencies.

`php composer.phar install`

If you want to use the autoloading provided by Composer, add the following line to your application file.

`require 'vendor/autoload.php';`

You are now ready to use NeatCharts.

### Install NeatCharts manually

Just download the folder `NeatCharts` (in `src`) and place it alongside your php file. Add the following at the top of your PHP file:

```php
spl_autoload_extensions(".php");
spl_autoload_register();
```
This will automatically require the correct files when they are referenced, since the namespace and class names match the folder structure.

## Usage
```php
Header('Content-type: image/svg+xml; charset=utf-8');

$chart = new NeatCharts/LineChart($chartData, [ // all parameters optional
  'width'=>800,
  'height'=>250,
  'lineColor'=>"#1C75BC",
  'labelColor'=>"#777",
  'smoothed'=>false
]);
print $chart->render();
```

In your HTML:
`<img src="path to the PHP file">`
