使用CodeIgniter-Google-Maps-V3-API-Library在谷歌地图中显示距离比例？

Question

Is there a way that I could display the distance scale - in KM or Miles or anything reasonable - as it is shown in http://maps.google.com when using the CodeIgniter-Google-Maps-V3-API-Library ?

Edited

This is what I have done :

    $this->load->library('googlemaps');

    $config['center'] = $center['latitude'].' '.$center['longitude'];
    $config['zoom']    = '5';
    $config['cluster'] = false;
    $config['disableScaleControl'] = false;
    $config['scaleControlPosition'] = 'TOP_RIGHT';
    $config['disableDefaultUI']=false;

    $this->googlemaps->initialize($config);

And this is what I am getting :

The mapOptions object has a scaleControl property that is set to false by default. Please see the documentation.
