axhspan-Demo

Erstellen Sie Linien oder Rechtecke, die die Achsen entweder in horizontaler oder vertikaler Richtung überspannen, und Linien, die die Achsen dann mit einer beliebigen Ausrichtung überspannen.

# Thick blue vertical line at x=0 that spans the upper quadrant of the yrange.

# Infinite black line going through (0, 0) to (1, 1).
