Highcharts Rounding Yaxis And Xaxis Digits

I am trying to round yaxis and xaxis down. For example 3843 should be 3.843 on the graph and tooltip show 3.843 k. I have got the tooltip working but cant get it to change the grap

Solution 1:

Use dataLabelsformatter to achieve desired result

plotOptions: {
    area: {
      dataLabels: {
        useHTML:true,
        enabled:true,
        formatter:function() {
          value=this.y;numericSymbolDetector=Math.abs(this.y);if(numericSymbolDetector>1000) {
            value=Highcharts.numberFormat(value/1000, 3, '.', '');
          }
          returnvalue
        },
        style: {
          color:'#c4c4c4',
          font:'5px Trebuchet MS, Verdana, sans-serif'
        }
      },
      //enableMouseTracking:false
    },
    series: {
      lineColor:'#808080'
    }
  },

Solution 2:

If you want to display yAxis labels the same way, get rid of the formatter from the yAxis.labels object (then the thousand prefix will display). In case you want to display exact values of the points as yAxis labels, you can update tickPositions array on load event and format them adequately. Take a look at the example below.
