Solution

You can update Code as

var data_orange = [
  ['tw-pt', 1],
  ['tw-ml', 1],
  ['tw-il', 1]
];
var data_cabbage = [
  ['tw-hl', 1],
  ['tw-nt', 1]
];
var data_peanut = [
  ['tw-tw', 1],
  ['tw-tp', 1]
];

var all_data = [
  ['tw-pt', 1],
  ['tw-ml', 1],
  ['tw-il', 1],
  ['tw-hl', 1],
  ['tw-nt', 1],
  ['tw-tw', 1],
  ['tw-tp', 1],
]
var data_series = [{
  name: 'orange',
  data: data_orange
}, {
  name: 'cabbage',
  data: data_cabbage
}, {
  name: 'peanut',
  data: data_peanut
}, {
  name: 'All',
  data: all_data,
}];
var chart;

function createChart(chartData) {
  // Instanciate the map
  chart = new Highcharts.mapChart('container', {
    chart: {
      borderWidth: 1
    },

    title: {
      text: 'December product map'
    },
    subtitle: {
      text: 'https://stackoverflow.com/questions/47646879/cant-show-the-color-in-interactive-highchart-choropleth-map'
    },

    legend: {
      enabled: false
    },
    mapNavigation: {
      enabled: true,
      buttonOptions: {
        verticalAlign: 'bottom'
      }
    },
    series: [{
      name: 'Country',
      mapData: Highcharts.maps['countries/tw/tw-all'],
      data: chartData,
      dataLabels: {
        enabled: true,
        color: '#FFFFFF',
        formatter: function() {
          if (this.point.value) {
            return this.point.name;
          }
        }
      },
      tooltip: {
        headerFormat: '',
        pointFormat: '{point.name}'
      }
    }]
  });

}

window.updateChart = function(selection) {
  if (selection == "") {
    createChart(data_series[3].data);
  } else if (selection == "orange") {
    createChart(data_series[0].data)

  } else if (selection == "cabbage") {
    createChart(data_series[1].data)
  } else if (selection == "peanut") {
    createChart(data_series[2].data)
  }

}

updateChart("");
