            min: 0,
            max: 100,
            value: 78,
            options: {
                adjustable: true
            }
        }).draw().on('adjustbegin', function (obj)
        {
            // ...
        }).on('adjust', function (obj)
        {
            // ...
        }).on('adjustend', function (obj)
        {
            // ...
        });
    })
</script>

The RGraph adjusting events

There are three RGraph events associated with adjusting. The adjustbegin event fires when adjusting begins. Much like the mousedown event. The adjust event fires during adjusting, much like the mousemove event. The adjustend event fires when adjusting is finished, much like the mouseup event.
