pgfplot: zwei Achsen, beide plotten Y-Raster aktiviert, überlappendes Diagramm

Question

Yaxis1 Ygrid wird hinter dem gestapelten Diagramm angezeigt, Yaxis2 Ygrid wird jedoch über dem gestapelten Diagramm angezeigt.

Voraussetzung: Beide Raster müssen sich auf der Rückseite beider Parzellen befinden.
