C3.js change label position of Line Chart Y axis t

问题:

I need to change the Y axis's label position upon the Y axis, the current six position options can't meet my scenario, I also tried to customize it with d3 but still without luck.

I created a plnkr demo, and also submit an issue in github.

  var chart = c3.generate({ 
  data: {
      columns: [
          ['data', 30, 200, 100, 400, 150, 250]
      ]
  },
  axis: {
      y: {
          label: {
              text: 'Y Axis Label',
              position: 'outer-top'
          } 
      }
   }
 });

Does any one know how to do it?

Thanks very much in advance.

Unlike what you said, you can customize it with D3. Just select the label (by class) and set the transform:

d3.select(".c3-axis-y-label").attr("transform", "translate(25,30)")

here is the demo:

// Code goes here
(function() {

  var chart = c3.generate({
    padding: {
      top: 10
    },
    data: {
      columns: [
        ['data', 30, 200, 100, 400, 150, 250]
      ]
    },
    axis: {
      y: {
        label: {
          text: 'Y Axis Label',
          position: 'outer-top'
        }
      }
    }
  });

  d3.select(".c3-axis-y-label").attr("transform", "translate(25,30)")


})();
