Material Design Widgets: JSON Chart Widget

[Atredis]

Hallo.
Ich bin noch in der Anfangsphase was das alles hier betrifft.
Ich bin auch recht unwissend was JAVA betrifft und klicke mich mehr durch Blockly daher scheinen deine Widgets sehr Interessant zu sein.

Das was ich jetzt nirgendwo gefunden habe ist wie ich Daten in das JSON Chart Widget rein bekomme.

Gehe einfach einmal davon aus das ich total unwissend bin.

Ich habe mir selber über Blockly einen JSON Datensatz erzeugt.

Welches Format muss das JSON haben um Angezeigt zu werden.

Mein Datensatz enthält

[{"Zeitstempel":"1586556000000","Wert":"15","Uhrzeit":"00:00"},{"Zeitstempel":"1586556060000","Wert":"15","Uhrzeit":"00:01"},{"Zeitstempel":"1586556120000","Wert":"15","Uhrzeit":"00:02"},{"Zeitstempel":"1586556180000","Wert":"15","Uhrzeit":"00:03"},{"Zeitstempel":"1586556240000","Wert":"15","Uhrzeit":"00:04"},"
.
.
.
{"Zeitstempel":"1586642040000","Wert":"1434","Uhrzeit":"23:54"},{"Zeitstempel":"1586642100000","Wert":"1435","Uhrzeit":"23:55"},{"Zeitstempel":"1586642160000","Wert":"1436","Uhrzeit":"23:56"},{"Zeitstempel":"1586642220000","Wert":"1437","Uhrzeit":"23:57"},{"Zeitstempel":"1586642280000","Wert":"1438","Uhrzeit":"23:58"},{"Zeitstempel":"1586642340000","Wert":"1439","Uhrzeit":"23:59"},{"Zeitstempel":"1586642400000","Wert":"1440","Uhrzeit":"00:00"}]

Wie bekomme ich diese Werte angezeigt und wie kann ich auswählen was angezeigt wird.

In diesem Fall möchte ich die Werte in Abhängigkeit von der Uhrzeit angezeigt bekommen.

Ist dieses möglich oder denke ich einfach nur Falsch.

Irgendwo muss ich doch angeben was Angezeigt werden soll.

Danke schon einmal für eine mögliche Erklärung.

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

@Scrounger sehr cool. kannst du mir das Beispiel aud dem bild geben

Beispiel in dem es enthalten ist findest du hier:

@Scrounger

ich habe leider das gleiche Problem wie @Stephan-Schleich

Ich wollte mir den UV Index vom OpenUV Adapter auslesen und habe versucht das Script von dir anzupassen.
Anpassungen erfolgten in folgenden Zeilen:
7
22
28
19
24-31
39

Die Daten sollen aus folgenden Datenpunkt vom History Adapter geholt werden:
"openuv.0.UV"

// imports NPM Module
const moment = require("moment");
moment.locale("de");

Wo mache ich hier bitte den Fehler?

Datenpunkte lassen auch nur unter userdata anlegen.

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

Welches Format muss das JSON haben um Angezeigt zu werden.

steht in der Doku:
https://github.com/Scrounger/ioBroker.vis-materialdesign#json-chart

Schau dir die Beispiele an:
https://forum.iobroker.net/topic/26925/test-adapter-material-design-widgets-v0-2-x/857

@Stephan-Schleich sagte in Material Design Widgets: JSON Chart Widget:

Ich hab nur einen Ladekreis wenn ich einen JSON DP hinterlege

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

ich habe leider das gleiche Problem wie @Stephan-Schleich

Benötige den json string und die skripte, damit ich weiterhelfen kann.

[Oli]

@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.

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.

Das ist er.
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:

Vor den Updates

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