我刚刚开始使用c3.js,我还没弄明白如何在x轴上指定刻度值.值为type1,type2,type3 ……这是我的代码：

    $(document).ready(function(){
      var mammoReconstructionsAcceptedChart = c3.generate({
        bindto: '#mammo_reconstructions_accepted',
        data: {
          x: 'x',
          columns: [
            ['x', 'type1', 'type2', 'type3', 'type4', 'type5', 'type6'],
            ['data1', 30, 200, 100, 400, 150, 250]
          ]
        },
        axis: {
          x: {
            tick: { format: d3.format("") }
          }
        }
      });
    });

解决方法:

这完全没问题.我基于C3.js网站上的Category Axis Example.

$(document).ready(function() {
  var mammoReconstructionsAcceptedChart = c3.generate({
    bindto: '#mammo_reconstructions_accepted',
    data: {
      columns: [
        ['data1', 30, 200, 100, 400, 150, 250]
      ]
    },
    axis: {
      x: {
        type: 'category',
        categories: ['type1', 'type2', 'type3', 'type4', 'type5', 'type6']
      }
    }
  });
});
