I have built a a higcharts charts and I am displaying them one at a time on mouseover. The jquery creates a floting div (depending on the cursor) with a border line

1px solid black

and then the highchart method is being called to draw the chart.

The thing is that highcharts exceed and left and bottom border is not shown.

I tired 'margin' :

chart:
    {
      renderTo: 'graph',
      defaultSeriesType: 'line',
      zoomType: 'x',
      margin: [ 10, 10, 10, 10]
    },

and still it does the same thing.
