I am trying to display only one name at each end of the bar's chart.
I send data from a controller (i am using zend) :

```
$chartsData['project'][] = array('riri', 45);
$chartsData['project'][] = array('fifi', 120);
$chartsData['project'][] = array('loulou', 3);

```

And I got this:

As you can see, everything is fine and the data are correct. Except the name at the end of the bar. I just want to show one name each bar (riri, fifi, loulou). Presently, i got this in my js file : 

```
        plotOptions: {
            bar: {
                color : '#4572A7',
                dataLabels: {
                    enabled: true,
                    borderWidth: 0,
                    format: '{series.name}' 
                }
            }
        },           

```

I try to change the value in `{series.name}` to put `{x}` or `{y}` but i only got the number.
