Question

I “faked” a clear circle as markers by setting the fillColor the same as the background. It works just fine. Now, on hover, I am trying to get the circle to fill with the series color. I can’t set it as null, as then it takes the background color still.

Any ideas?

Here is my chart code (live version here:http://jsbin.com/ukabob/2/edit):

$(function () {
var chart;
$(document).ready(function() {
    chart = new Highcharts.Chart({
        chart: {
            renderTo: 'container',
            type: 'line',
            backgroundColor: '#E9E7DC'
        },
        colors: ['#A74B59', '#46C4B7', '#EDBA70'],

              formatter: function() {
                return '<div style="font-size:22px; font-family: \'Advent Pro\', sans-serif;">'+
                    this.value +'</div>';
              },

                lineWidth: 2,

I’m not sure how this should look like, but I see two ways:

• you want empty space between lines, and on hover fill that space, in that case you can use this solution: http://jsbin.com/ukabob/3/edit As you can see, for each series you have to set marker options:

      series: [{    
          data: [],
          marker: {
              states: {
                  hover: {
                    fillColor: yourColor
                  }
              }
          }
      }]
  

• you don’t want empty space between lines, in that case you can set radius of marker to 0, see: http://jsbin.com/ukabob/5/edit

    plotOptions: {
        series: {
          marker: {
              radius: 0,
              lineColor: null, // inherit from series
              symbol: 'circle',
              states: {
                  hover: {
                    fillColor: null,
                    fillColor: null,
                    lineWidth: 2,
                    radius: 6
                  }
              }
          }
       }
    }
