[Solved]-Highcharts - Legend Positioning outside the chart-Highcharts

Have you tried something like this?

"legend": {
 "align": "left",
  y: -20 // <=== use a negative value 
}

it seems like you need to set 'floating: false' http://jsfiddle.net/hx86zhob/1/

legend{
    layout: 'vertical',
    align: 'right',
    verticalAlign: 'middle',
    floating: false
}
