    yAxis: {
        title: {
            text: null
        }
    },
    series: [{
    name: 'Year 1800',
    data: [107, 31, 635, 203, 2]
    }, {
    name: 'Year 1900',
    data: [133, 156, 947, 408, 6]
    }, {
    name: 'Year 2000',
    data: [814, 841, 3714, 727, 31]
    }, {
    name: 'Year 2016',
    data: [1216, 1001, 4436, 738, 40]
     }]
    });
    }

But when you try change this type to chart Pie so this is not work. How can I fix this please?

Answer 1

The pie chart type has only one series, so to change color you have to use update method on a point:

$("#but").on("click", function() {
  var point = chart.series[0].points[1];
  point.update({
    color: 'red'
  });
});
