Retrieving data from Google Analytics API and show results

[eluser]Ludovic-r[/eluser]
I need your help because I'm stuck on how to get secondary datas from Google API and show them on a graph, let me explain :

I've successfully retrieved "visits" datas from the Google Analytics API and show them on my chart with this code :

Code:

$report3 = $ga->getReport(
                array('dimensions'=>urlencode('ga:date'),
                    'metrics'=>urlencode('ga:pageviews,ga:visits'),
                    'filters'=>urlencode(''),
                    'sort'=>'ga:date'
                    )
                );

Which give me an array like :

Code:

[20110726] => Array
    (
        [ga:pageviews] => 0
        [ga:visits] => 0
    )

Then I put these informations on the chart with :

Code:

[removed]
    var ga_data = [
    <?php
        $str = "";
        foreach ($report3 as $value)
            $str.="{$value["ga:visits"]},";
        $str = rtrim($str,",");
    echo $str;
    ?>
    ];
[removed]

And finally :

Code:

// Create the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Month');
data.addColumn('number', 'visits');
data.addRows(ga_data.length*1);
for (i=9; i<ga_data.length; i++){

    data.setValue(i, 0, 'DATE NEEDED');
    data.setValue(i, 1, ga_data[i]);
}

The only problem is that I need to show the DATE : ([20110726] => Array ( [ga:pageviews] => 0 [ga:visits] => 0 )) on the chart like I do with visits

Any help will be very very appreciated ! Thanks !!!
