Changing HighCharts background color?

Question

I don't really know how to do this.

I need to change background color of this highcharts chart:

http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/polar-spider/

But I don't seem to be able to do so - there doesn't seem to be any clear place to put the background color setting?

I've tried to write many different values in this section:

chart: {
        polar: true,
        type: 'line'
},

But it didn't do anything ( it occasionally broke this script ).

Do I need to change it somewhere in the included .js files? Or can it be done from the level of this loaded script?

JS is really confusing. Can anyone help me?

Take a look at the Highcharts API here: https://api.highcharts.com/highcharts/chart.backgroundColor and you will see it's a property of the chart object that can take a solid color:

{
  chart: {
     backgroundColor: '#FCFFC5',
     polar: true,
     type: 'line'
  }
}

Or Gradiant:

{
  chart: {
    backgroundColor: {
       linearGradient: [0, 0, 500, 500],
       stops: [
         [0, 'rgb(255, 255, 255)'],
         [1, 'rgb(200, 200, 255)']
       ]
     },
     polar: true,
     type: 'line'
  }
}
