Javascript 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

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;
}
}
```
