Answer 1

you can hide value by 'false'

data: [[0, 0, false], [0, 1, 2], [0, 2, 3], [0, 3, 4], [0, 4, 5], [1, 0, 2], [1, 1, 4], [1, 2, 6], [1, 3, 8], [1, 4, 10], [2, 0, 3], [2, 1, 6], [2, 2, 9], [2, 3, 12], [2, 4, 15], [3, 0, 4], [3, 1, 8], [3, 2,12], [3, 3, 16], [3, 4, 20], [4, 0, 5], [4, 1, 10], [4, 2, 15], [4, 3, 20], [4, 4, 25]

Answer 2

There is a backgroundColor tag you can use: (http://jsfiddle.net/aeP4E/)

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

Answer 3

That's you want `

chart: {
            polar: true,
            type: 'line',
            backgroundColor:'rgba(255, 255, 255, 0.1)'
        }

`

Answer 4

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'
  }
}

Answer 5

Demo

You can data: [[0, 0, true], you can hide value by 'false' and you can set your gradient by

  colorAxis: {
        min: 0,
        stops: [
         [0, '#5DBA76'],
        [0.4, '#ffff00'],
        [0.8, '#F30000']
    ],
        minColor: '#ff0000',
        maxColor: '#ffff00'
    },

Thanks :)
