d3js Timeline-Diagramm - mit einem Rechteckblock für ein Peeling

Ich möchte ein Zeitdiagramm mit nur einem Rechteckblock unten erstellen. Das wird als Master Scrubber verwendet.

// aktuell - http://jsfiddle.net/NYEaX/2427/

Wo sich der Schrubbabschnitt befindet - Ich möchte nur ein Basisrechteck haben. Welche Art von Änderungen sollte ich an der aktuellen Codebasis vornehmen?

so ist es eher so

Erweitern Sie das Snippet

Das neueste Design ist so

und da der Scrubber mehr Details anzeigt - wie ein Datumsbereich von 1 Monat - wird das Format der Skala detaillierter

Hallo, ich habe nicht verstanden, was Sie tun möchten. Möchten Sie den Abschnitt "Person p" aus dem Diagramm entfernen?

Wurzel

Haben Sie nur ein einzelnes Rechteck - einen generischen Scrubber - anstelle einer Mini-Version des Hauptdiagramms

Rob

so jsfiddle.net/2mvhjr7z/2

Rob

Wollen Sie die gelben und rosa Balken entfernen und eine dünne kleine Linie wie in der bereitgestellten Geige beibehalten?

Wurzel

ja - so ähnlich - jsfiddle.net/KgomDr/46uLtcvf

Rob

Antworten:

Obwohl mir nicht klar ist, was genau Sie erreichen möchten, gehe ich davon aus, dass Sie ein generisches Basisrechteck benötigen.

Ich habe die Codezeile entfernt, um die Beschriftung dieses Basisrechtecks anzuzeigen, und die Höhe des Mini-Abschnitts aktualisiert.

Lassen Sie mich wissen, wenn Sie dies nicht erwarten.

Bitte überprüfen Sie meine Geige.

ja - so ähnlich - mit einem Konfigurationsobjekt - jsfiddle.net/KgomDr/46uLtcvf

Rob

Meint? Was ist das Problem in meinem Ergebnis? Können Sie erklären, was genau fehlt?

Mayank Patel

Ja. Das ist möglich. Können Sie Ihr Datum als dateObjekt anstelle von Zeitstempeln speichern ?

Mayank Patel

Nun - ich versuche es anhand möglicher realer Daten zu modellieren - wie einfach ist die Konvertierung zwischen Zeitstempel / Datumsobjekt - ist es möglich, dies dem Konfigurationsobjekt hinzuzufügen?

Rob

jsfiddle.net/m0czbuxs/2 - Ich habe das Konfigurationsobjekt zum Dom hinzugefügt, damit alles an einem Ort ist. - Weitere Klassen müssen hinzugefügt werden, damit Stile im CSS konfiguriert werden. Ich habe mehr Daten hinzugefügt, um der tatsächlichen Datenstruktur näher zu kommen - aber der Mini-Halter mit dem Scrubber erstellt immer noch falsch vertikale Linien. Ich habe einen Tooltip zu dieser Version hinzugefügt - jsfiddle.net/m0czbuxs/3

Rob

Aus Ihrer Frage geht nicht hervor, was Sie mit dem Basisrechteck meinen. Sie können jedoch alles ausblenden, was Sie nicht sehen möchten, indem Sie die Deckkraft .style("opacity", 0)für jedes Element , das Sie ausblenden möchten, auf 0 setzen (ich habe so ziemlich alles versteckt , mit Ausnahme der Bereichslinie, die ich für das Basisrechteck am besten erraten habe ). Sie können es weiterhin wie zuvor auswählen und schrubben:
