# EDD_Graph

 The EDD\_Graph class, introduced in EDD version 1.9, is used for easily building graphs of data. For example, the earnings / sales reports graphs seen in Downloads → Reports are created using EDD\_Graph. The class can be used by extensions to quickly graph any data set.

 
 A simple example looks like this:

```
$data = array(
	'Your Graph Label Here' => array(
		array( 1, 5 ),
		array( 3, 8 ),
		array( 10, 2 )
	),
	'Second Label Here' => array(
		array( 1, 7 ),
		array( 4, 5 ),
		array( 12, 8 )
	)
);
$graph = new EDD_Graph( $data );
$graph->display();<br></br>
```

 Each inner array represents a data point on the graph and should be structured like this:

```
array( 'value on x axis', 'value on y axis' )
```

 Graphs can contain one one or more lines. To add multiple lines, simply add additional inner arrays, as shown in the example above.

 Along with the data points, EDD\_Grap allows you to control various options of the graph by using the *set()* method. For example:

```
// Example with options set to other than default:
$data = array(
    'Line Label' => array(
        array( 1, 5 ),
        array( 3, 8 ),
        array( 10, 2 )
    ),
    'Second Line Label' => array(
        array( 1, 7 ),
        array( 4, 5 ),
        array( 12, 8 )
    )
);
$graph = new EDD_Graph( $data );
$graph->set( 'bgcolor', '#000' );
$graph->set( 'color', '#fff' );
$graph->display();<br></br>
```

 The available options are:

- y\_mode
- x\_mode
- y\_decimals
- x\_decimals
- y\_position
- time\_format
- ticksize\_unit
- ticksize\_num
- multiple\_y\_axes
- bgcolor
- bordercolor
- color
- borderwidth
- bars
- lines
- points

 See the [Flot API reference](https://github.com/flot/flot/blob/master/API.md) for the possible values each of these can receive.

 Note, if you want to display a graph on the front end, you will need to include *includes/admin/reporting/class-edd-graph.php* first.
