Highchart 饼图联动

感觉好久没有更新博客了，最近一直忙着毕业论文，紧接着就开始搭建数据库，实在抽不出时间写。

正好趁着做数据库，写一写关于Highchart里两个饼图之间的互动。

用到的数据比较大，我也懒得修饰了，涉及到两个pie图的div，分别是 pie_container 和 signature_container。

先说明一下画 signature_container  时为了和  pie_container 互动，定义了一个函数，画图的数据利用 ajax 读取:

function signature_pie(cancer_type){
  var data_arr = [
        {name: "gene", y: 0.4},
        {name: "protein", y: 0.2},
        {name: "lncRNA", y: 0.1},
        {name: "miRNA", y: 0.1},
        {name: "mutation", y: 0.1},
        {name: "methylation", y: 0.1}
      ];
      var options = {
          chart: {
            plotBackgroundColor: null,
            plotBorderWidth: null,
            plotShadow: false,
            type: 'pie',
          },
          title: {
            text: 'signature type statistics',
            style:{
              fontSize: "20px"
            },
            y: 10,
            x:-5
          },
          tooltip: {
            pointFormat: 'Cohort precentage: <b>{point.percentage:.1f}%</b>'
          },
          credits: {
              enabled: false
          },
          plotOptions: {
             pie: {
                allowPointSelect: true,
                cursor: 'pointer',
                events: {
                  click: function(event){
                    var signature_type = event.point.name;
                    document.getElementById("choose_signature_type").innerHTML = "<b>" + signature_type + "</b>";
                  }
                },
                dataLabels: {
                    enabled: false,
                    color: "black",
                    format: '<b>{point.name}</b>: {point.percentage:.1f} %',
                    }
              }
        },
        series: [{
          names: 'signature stat',
          data: data_arr
        }]
      };
  if(cancer_type == "ALL"){
    Highcharts.chart('signature_container', options);
  } else {
    $.ajax({
        url: '../data/test.txt',
        dataType: 'text',
        type: 'GET',
        async: false,
        success: function(data) {
          var lines = data.split('
');
          for(var index = 1; index < (lines.length - 1); index++){
            var info = lines[index].split('	');
            if(info[0] == cancer_type){
              for(var i = 1; i < (info.length-1); i++){
                options.series[0].data[i-1].y = parseFloat(info[i]);
                }
                Highcharts.chart('signature_container', options);
                break;
              }
          }
        }
      });
  }
}

　　

下面是 pie_container 的 options:

var options = {
    chart: {
      plotBackgroundColor: null,
      plotBorderWidth: null,
      plotShadow: false,
      type: 'pie',
    },
    title: {
      text: 'cancer type statistics',
      style:{
        fontSize: "20px"
      },
      y: 10,
      x:-5
    },
    tooltip: {
      pointFormat: 'Type is <b>{point.type}<b><br/>Cohort precentage: <b>{point.percentage:.1f}%</b>'
    },
    credits: {
        enabled: false
    },
    plotOptions: {
       pie: {
          allowPointSelect: true,
          cursor: 'pointer',
          events: {
            click: function(event){
              var cancer_type = event.point.name;
              document.getElementById("choose_cancer_type").innerHTML = "<b>" + cancer_type + "</b>";
　　　　　　　　 //利用signature_pie()函数，根据对应数据重新画一个pie图
              javascript:signature_pie(cancer_type);
              var index = event.point.index;
              options.series[0].data[index]['selected'] = 'true';
              options.series[0].data[index]['sliced'] = 'true';
              Highcharts.chart('pie_container', options);
              options.series[0].data[index]['selected'] = '';
              options.series[0].data[index]['sliced'] = '';
            }
          },
          dataLabels: {
              enabled: false,
              color: "black",
              format: '<b>{point.name}</b>: {point.percentage:.1f} %',
              }
