@Scrounger

danke schon mal im Voraus, das Script ist bereits im Spoiler vorhanden.

Was meinst du mit json string?

Scrounger

@Oli
Habs nur halb gelesen
Alle Infos da, schaus mir an.

Oli

@Scrounger

danke

Scrounger

@Oli
axislabel fehlt

Edit:
Oh sollte echt mal richtig lesen. Du verwendest timestamps für die x-achse.

Hast nen tipp fehler:

"type": "linie",

muss

"type": "line",

Das steht auch in der console log, wenn man den debug modus aktiviert hat.

Oli

@Scrounger

super, danke funktioniert

Oli

@Scrounger

hast du auch mal nach dem 2 Thema aus meinem Poste geschaut?

Wenn ich im Script Zeile 7

let strukturChannel = '0_userdata.0.Wetter.Diagramme.UvIndex';

"0_userdata.0.Wetter.Diagramme.UvIndex" gegen "javascript.0.Wetter.Diagramme.UvIndex" tausche bringt er mir folgende Warnungen und die Datenpunkte werden nicht angelegt

@Oli
Edit:
Ok Frage betrifft Wigdet aber auch nciht, sondern ist eine Frage bzgl. skripts:

Es wird in dem Beispiel nur '0_userdata.0' unterstützt, weil es in zeile 235 hard coded ist:

   const where = '0_userdata.0'

Boronsbruder

Ich hab mal ne Frage...
Nach nem Update von Node und NPM und einiger npm module (ich glaube "moment" war auch mit dabei) hat sich mein "Wettertrend" von ehemals

nach

geändert.

Der Tooltip ist jetzt auch leer...

Das Javascript, das den JSON erstellt wurde nicht geändert.

und nun die Frage: "Warum ist das so?"

Das ist der JSON

Danke an alle, bei denen ich geklaut habe

Boronsbruder

Also, das mit dem leeren Tooltip konnte ich lösen:

tooltip_text: "Temperatur",

in

tooltip_title: "Temperatur",

geändert.

Als ich zum Testen noch

und es wird kein Tooltip mehr angezeigt.

Ob das damit zusammenhängt? keine Ahnung

Boronsbruder

Die Firefoxfehler hab ich jetzt auch weg:
Wer lesen kann ist klar im Vorteil....
xAxis_tooltip_timeFormats "type" ist halt "string" und nicht "object"...

Aber das Hauptproblen, dass die Wochentage nicht mehr angezeigt werden, besteht leider immer noch...

Boronsbruder

So, wieder einen Schritt weiter...

Nach dem ich den Eintrag bei xAxis_tooltip_timeFormats -> minute: in "dd.[\n]H:mm" geändert habe, ist meine Beschriftung wieder im richtigen Format.

Warum er aber nun das "Minute"-Format nutzt, erschließt sich mir nicht, da die Abstände der Timestamps immer noch stündlich sind.

Was aber leider immer noch nicht funktionert ist, daß er jetzt die Beschriftung nicht mehr im 2-stündlichen Abstand schreibt, sondern jede Stunde.
Der Haken bei "Automatische Überspringen von Beschriftungen auf der X-Achse" macht keinen Unterschied.

Was mir auch noch aufgefallen ist, dass die Beschriftung nicht mehr "synchron" zu den Daten ist, wenn man im Widget nicht explizit die "maximale Anzahl der Beschriftungen" festlegt!

Ohne Eintrag:

Mit maximale Anzahl der Achsenbeschriftung -> 35:

P.S. ist der Thread hier eigentlich tot, oder interessiert das nur niemand

Scrounger

@Boronsbruder
Ne nicht tot, hab immer die Hoffnung das auch jemand anderes antwortet

Poste mal den json string für den Chart, dann schau ich es mir an.

Dank dir schon mal im Vorraus

@Boronsbruder sagte in Material Design Widgets: JSON Chart Widget:

Weil die API immer versucht die Achse optimal zu erstellen. Wenn du jetzt wieder Minuten im timeformat aktivierst, siehst du das die Achsenschritte in Minuten sind.

Was aber leider immer noch nicht funktionert ist, daß er jetzt die Beschriftung nicht mehr im 2-stündlichen Abstand schreibt, sondern jede Stunde.

Bei 35 Werten (= Stunden) alle zwei Stunden anzeigen, muss du bei maximale Anzahl der Beschriftung die Hälfte eintragen, also 17 / 18 Kommawerte gehen nicht.

Der Haken bei "Automatische Überspringen von Beschriftungen auf der X-Achse" macht keinen Unterschied.

Was mir auch noch aufgefallen ist, dass die Beschriftung nicht mehr "synchron" zu den Daten ist, wenn man im Widget nicht explizit die "maximale Anzahl der Beschriftungen" festlegt!

Gleiche Ursache wie oben, er nimmt hier Minute aber du blendest sie aus.
Hier mal zwei screenshots dazu:

Wie du erkennst passt er je nach Größe automatisch die Achse an.

So jetzt noch die gute Nachricht. Hab noch eine Möglichkeit in der API entdeckt, wodurch das besser geht. Ist in der kommenden Verison enthalten.

Boronsbruder

@Scrounger
Danke für die Infos!

Kann ich der Api vorgeben, ob ich stündlich oder minütlich haben will?
Vorher war die Darstellung ja so:

Ja die API bietet die Möglichkeit, gibt aber verschiedene Gründe warum ich das nicht einbauen möchte. Macht die Einstellungen für die User nochmals komplizierter.

Hi zusammen,
ich versuche aus o.g. Beispiel ein bar chart zu erstellen, welches als grouped bar dargestellt wird. In meinem Fall also Energiewerte der PV-Anlage pro Tag innerhalb einer Woche. Dazu müssen Produktion, Einkauf, Verkauf, etc. gruppiert angezeigt werden. Funktioniert das überhaupt? Anhand der Doku hier lässt sich vermuten, dass es zumindest noch nicht möglich ist.

Das geht bereits, nennt sich allerdings stacked bar chart:

@Scrounger
Super, vielen Dank für die schnelle Antwort.
Kannst du mir noch sagen, warum an den Rändern des Graphen die Balken abgeschnitten werden? Das Datum ist ja mittig angeordnet, weshalb links und rechts jeweils nur die Hälfte (zwei der vier) angezeigt wird.

Der Code für einen der Balken sieht so aus (analog dazu die anderen drei):

{"data":[{"t":dateToday-(86400000*4),"y":energyToGrid[4]},{"t":dateToday-(86400000*3),"y":energyToGrid[3]},{"t":dateToday-(86400000*2),"y":energyToGrid[2]},{"t":dateToday-(86400000),"y":energyToGrid[1]},{"t":dateToday,"y":energyToGrid[0]}],"type":"bar","barIsStacked":"true","barStackId":1,"yAxis_id":1,"legendText":"","tooltip_title":"To","tooltip_MaxDigits":2,"tooltip_AppendText":" Wh","yAxis_show":"false","xAxis_bounds":"data","xAxis_timeFormats":{"millisecond":"H:mm:ss.SSS","second":"H:mm:ss","minute":"dd.[\\n]H","hour":"dd.[\\n]H:mm","day":"dd[\\n]DD.MM","week":"dd[\\n]DD.MM","month":"MMM[\\n]YYYY","quarter":"[Q]Q - YYYY","year":"YYYY"}},

Habe vergeblich nach etwas wie "border","offset" oder "distance" gesucht.

shortcircuit0815

Hat jemand zufällig eine Idee oder ein ähnliches Problem?
Selbst wenn ich in den Attributen des JSON Chart's Abstände eintrage, wird zwar das Diagramm um den Wert kleiner, aber beim ersten und letzten Tag sind jeweils die beiden äußeren der vier Balken abgeschnitten. Die zugehörigen Werte sind gerade noch so zu erkennen.
Im folgenden Bild sieht man den Rahmen des Charts. Weit innerhalb davon das Balkendiagramm.
