@damrak2022 Gut - Du hast es geschafft.

und dann das gleiche nochmal: Hier zum Import

Ausgabe wieder mit Change Node und debug Node.

@damrak2022 Sehr gut.

Nun dann machen wir da weiter, wenn Du mir grundsätzlich sowohl mit Worten als auch mit dem Aufbau erklärst, was die Chart Node erwartet. Wir können das gerne auch mit der Temperatur aus der Küche machen. Der Aufbau des Arrays für die Chart Node ist ja immer gleich. Also wie siehst der Aufbau aus - richte Dich an dem Screenshot aus Steves oder dem Objekt das Du schon erstellt hast.

Du kannst es ja bereits im JSONATA try machen und dann nimmst Du halt auf der Eingangsseite das Objekt aus dem Küchenthermometer.

[Damrak2022]

@mickym Die Chart Node erwartet einen Zahlenwert. Den Flow für die Küche habe ich so nachgebaut:

[Damrak2022]

@mickym Den Exerciser habe ich mal geöffnet, aber noch nichts eingetragen.

[mickym]

@damrak2022 Nun dann sollte der Chart durch die aktuellen Werte bereits aufgebaut werden. Es geht ja nur darum, dass Du die historischen Daten, wenn Du Neustart in die Chart Node eingibst. - Also der Chart sollte ja bereits funktionieren. Mach doch mal ein Screenshot.

[mickym]

@damrak2022 sagte in Visualisierung mit Node Red erstellen:

@mickym Den Exerciser habe ich mal geöffnet, aber noch nichts eingetragen.

Nun dann kopiere links in das Eingabefeld das Array, mit dem Du arbeiten willst.

[Damrak2022]

@mickym

[mickym]

@damrak2022 Nun wie heisst dann deine "Datenserie" ?

[Damrak2022]

@mickym Langsam, dann muss ich den Wert vom Array kopieren und nicht den Pfad, richtig?

[mickym]

@damrak2022 Zum Ausprobieren ja - da musst Du auf eine externe Webseite den Inhalt kopieren, denn Du ändern willst. Die externe Webseite hat sicher keinen Zugriff auf Dein Node Red.

[Damrak2022]

@mickym Habe ich

Ich verstehe die Bedeutung von "result" und "table" noch nicht

[mickym]

@damrak2022 sagte in Visualisierung mit Node Red erstellen:

@mickym Habe ich

Wo hast Du es denn hin kopiert?

[Damrak2022]

@mickym links rein

[mickym]

@damrak2022 Ja dann mach halt einen Screenshot von der Webseite dann sehe ich das. Du könntest mir das ja auch hier in CodeTags reinkopieren, dann kann ich es auch auf die try Seite kopieren.

[mickym]

@damrak2022 Gut dann sollte Deine Webseite ja nun so aussehen:

[Damrak2022]

@mickym Korrekt

[mickym]

@damrak2022 Gut was musst Du in die Change Node eingeben, wenn Du mit JSONATA - das Eingangsobjekt unverändert wieder ausgeben möchtest?

[Damrak2022]

@mickym Auf der Exercise Seite ist es das $ Zeichen. Change Node weiß ich gerade. nicht, hattest Du mir aber gestern gesagt, das weiß ich noch
