Highcharts舍入yaxis和xaxis数字

Question

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 graphs yaxis and xaxis value so that the graph can show all sides fully.

As you can see here: http://jsfiddle.net/kzL0phfu/

This is what xaxis looks like

yAxis: {
gridLineInterpolation: 'polygon',
lineWidth: 0,
min: 0,
gridLineColor: "#808080",
gridLineDashStyle: "Solid",
gridLineWidth: 2,
labels: {
  format: '{value:.2f}',
  style: {
    color: '#c4c4c4',
    font: '11px Trebuchet MS, Verdana, sans-serif'
  }
}
}

Answer 1

Use dataLabels formatter 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, '.', '') ;
          }
          return value
        },
        style: {
          color: '#c4c4c4',
          font: '5px Trebuchet MS, Verdana, sans-serif'
        }
      },
      //enableMouseTracking: false
    },
    series: {
      lineColor: '#808080'
    }
  },

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.
