Ich muss ein Liniendiagramm mit 5 Datensätzen von Trenddaten anzeigen. Jeder Datenwert entlang der Konturlinien muss an seinem jeweiligen Datenpunkt eine Datenwertbezeichnung aufweisen.

Leider kann ich in Charts.js keine Option finden, die diese Anforderung erfüllt.

Gibt es eine Problemumgehung, die mir helfen kann?

Ich habe das auch auf fiddle gepostet:http: //jsfiddle.net/s9eannLh

Vielen Dank
