Ich erstelle eine beamerPräsentation mit animierten tikzpictureUmgebungen. Im MWE besteht die obere Abbildung aus einem sich nie ändernden Diagramm und einem Punkt, der sich darauf bewegt. Da das Kompilieren des Diagramms lange dauert, habe ich es in einer Datei gespeichert, image.pdfdie ich in ein lade node. Leider habe ich keine Möglichkeit gefunden, das Bild ein für alle Mal zu laden: Meine aktuelle Lösung besteht darin, es bei jedem Schritt zu laden (also ungefähr 600 Mal ...).
Das untere Diagramm besteht aus einer Kurve, die \pgfplotsaus einer Datendatei gezeichnet wurde data.dat. Ich habe 5 verschiedene Datendateien (ich verwende dieselbe im MWE), die nacheinander mit geladen werden only. Für eine Datendatei zeichne ich einen animierten Punkt auf der Kurve. Auch hier habe ich keine andere Lösung gefunden, als die Kurve bei jeder Iteration (also etwa 600 Mal ...) zu zeichnen.
Insgesamt dauert die Kompilierung mehrere Minuten. Ich habe die Anzahl der Iterationen so reduziert, dass der bereitgestellte Code etwa 20 Sekunden dauern sollte.
Das sind also meine Fragen:
Wie kann ich das Bild ein für alle Mal in den oberen Plot laden?
Wie kann ich jede der fünf Kurven ein für alle Mal in das untere Diagramm eintragen?
Gibt es Unschönheiten im Code, die mir nicht aufgefallen wären?
animateinlineIch habe versucht, und multiframeinnerhalb von zu verschieben tikzpicture, was den Fehler verursacht hat:

Antwort1
Der statische Teil des Ganzen tikzpicture, also das obere Bild mit den Achsen und die unten dargestellte Kurve samt Achsen und Achsenbeschriftungen, kann in ein PDF XObject gespeichert werden mit demxsaveboxPaket.
Das tikzpictureso gespeicherte Bild kann als Hintergrundbild beim Plotten auf der Oberseite eingefügt werden.isoliertrote und bewegliche blaue Punkte zum Erstellen der Animationsrahmen.
Anders als beim Einfügen von Standard-Saveboxen wird beim Referenzieren von PDF-XObject-basierten Saveboxen der gespeicherte Code nicht in der PDF-Ausgabedatei repliziert.
Zum Originalcode der Frage waren einige Ergänzungen notwendig:
Die axisOption
scale only axis
für den Hintergrund und beim Plotten der isolierten Punkte, und
hide axis
beim Plotten der isolierten Punkte.
Die Achsenbereiche müssen aus den Eingangsdaten ermittelt werden, da diese beim Plotten der einzelnen Punkte als Achsenoptionen eingestellt werden müssen.
Darüber hinaus muss die untere linke Koordinate des Begrenzungsrahmens des Hintergrunddiagramms in TeX-Makros gespeichert werden, um die korrekte Platzierung des Hintergrundknotens in den Animationsrahmen zu gewährleisten.
