@ethicalsector,
If you like to show y-value without decimal point in toolTip and indexLabel, you can use yValueFormatString. Please take a look at this updated JSFiddle.
At the same time, to format x-value displayed in toolTip and indexLabel, you can set xValueFormatString according to your requirements and to format axis-labels, you can use valueFormatString.
