Can I use two different formatters for highchart tooltips?

Question

I have a highcharts table with two data series that use named values. In my tooltips for one series, I want to reference a data point from the series. So the solution in this answer: How to use a different formatter on Highcharts in each curve of the same graphic? doesn't help me. I need more than just tooltipText, I need a formatter:

For one:

formatter: function() {
    return this.x + ': ' + this.series.name +
    '<br> $' + Highcharts.numberFormat(this.y, 0);
     }

And for the other:

formatter: function() {
    return 'In ' + this.x + ' the median value was' + this.median + 
    'and the total $' + Highcharts.numberFormat(this.y, 0);                        
 }

Answer 1

Inside formatter this reffers to the focused serie, you can add an if/else inside the formatter and return a string for each one, like the following.

tooltip: {
    shared: false,
    formatter: function() {
        var text = '';
        if(this.series.name == 'MSFT') {
            text = this.x + ': ' + this.series.name +
                   '<br> $' + Highcharts.numberFormat(this.y, 0);
        } else {
            text = 'In ' + this.x + ' the median value was' + this.median +
                   'and the total $' + Highcharts.numberFormat(this.y, 0);
        }
        return text;
    }
}

You can easily define a toolip formatter for each series - see here: http://api.highcharts.com/highcharts/plotOptions.series.tooltip

{
  tooltip: {
          shared: true
  },
  series: {
     name: 'some series name',
     data: mydata,
     tooltip: {
        valueSuffix: ' bar'
     }
  }
}
