I’m not sure if it is the “best practice” but I was able to solve my problem via
toolTip:{
contentFormatter: function ( e ) {
var content = \” \”;
for (var i = 0; i < e.entries.length; i++) {
content += e.entries[i].dataSeries.name + \”<br/>Datum: \” +(new
Date(e.entries[i].dataPoint.x)).toLocaleString(\”de-DE\”) + \”<br/>Wert: \”
+(Math.round((e.entries[i].dataPoint.y)*100)/100);
content += \”<br/>\”;
}
return content;
