Sarliefer · 23. Oktober 2015

Hallo liebe Community,

ich bin absoluter html-Neuling und möchte gerne bisschen was ausprobieren. Und zwar gibt es eine Beispiel-Webapp die folgendermaßen ausschaut:
[Blockierte Grafik: http://fs5.directupload.net/images/151023/jl7mbsip.jpg]

Man kann mit der App Dateien empfangen wie z.B. diverse Messwerte. Allerdings beschränkt sich die Anzahl der zu empfangenen Werte auf lediglich eine Quelle. Daher auch nur ein Diagramm. Ich würde gerne mehrere Werte empfangen können und diese auch jeweils auf einem Diagramm wie oben dargestellt visualisieren. Die Diagramme würde ich zudem gerne untereinander anzeigen wollen (außer es gibt eine elegantere Lösung?).
Weiß jemand zufällig aus dem Stand was man dafür tun muss. Falls nötig kann ich gerne den Code dazu posten.

Ich würde mich sehr über eure Hilfe freuen. Vielen Dank schonmal!
