Question

我有一个散点图JSFIDDLE，每个节点需要代表3个值。我查看了一个D3js示例 - Pack Layout。

以下是C3js代码块

var chart_scatterplot = c3.generate({
  tooltip: {
    contents: function(d, defaultTitleFormat, defaultValueFormat, color) {

      var company = jsonfile[d[0].index].company;
      var mailCount = jsonfile[d[0].index].mailCount;
      var lastInteractedInDays = jsonfile[d[0].index].lastInteractedInDays;

      var companyData = "<table class='data-c3-table'><tr><td>" + company + "</td></tr><tr><td>" + mailCount + "</td></tr><tr><td>" + lastInteractedInDays + "</td></tr></table>"
      return companyData;
      //return (company+mailCount+lastInteractedInDays) // formatted html as youmailCount want
    }
  },
  point: {
    r: function(d) {
    console.log(d)
       return Math.random() * average;
     },
      focus: {
    expand: {
      enabled: false
    }
  }
  },
  data: {
    json: jsonfile,
    x: 'mailCount',
    keys: {
      value: ['mailCount', 'lastInteractedInDays'],
    },
    color: '#49B5A6',
    type: 'scatter'
  },
  axis: {
    x: {
      label: 'Interactions',
      tick: {
        fit: false
      }
    },
    y: {
      label: 'Days'
    }
  },
  legend: {
    show: true
  }
});

在小提琴中，每个节点应该像基于3个值的饼图。我该怎么做？

馅饼的分散？听起来很美味。 c3.js之类的内容不支持此级别的自定义。您最好的选择是直接构建d3.js：

        bottom: 30,
        left: 40
      },
      width = 500 - margin.left - margin.right,
      height = 500 - margin.top - margin.bottom;

    var x = d3.scale.linear()
      .range([0, width]);

    var y = d3.scale.linear()
      .range([height, 0]);
      
    var arc = d3.svg.arc()

    .innerRadius(0);

   var pie = d3.layout.pie()
    .sort(null)
    .value(function(d) { return d; });

    var color = d3.scale.category10();

    var xAxis = d3.svg.axis()
      .scale(x)
      .orient("bottom");

    var yAxis = d3.svg.axis()
      .scale(y)
      .orient("left");

    var svg = d3.select("body").append("svg")
      .attr("width", width + margin.left + margin.right)
      .attr("height", height + margin.top + margin.bottom)
      .append("g")

    var data = [{

      values: [32, 32, 40]

    x.domain([0, 10]);
    y.domain([0, 10]);

    svg.append("g")
      .attr("class", "x axis")
      .attr("transform", "translate(0," + height + ")")
      .call(xAxis);

    svg.append("g")

      .attr('class', 'pie')
      .attr('transform', function(d){

      })
      
    pies.selectAll(".arc")
      .data(function(d){

      })
      .enter()
      .append('path')
      .attr('d', arc)
      .style("fill", function(d, i) {

      });
  </script>
