tikz skalieren

Hallo, an der Achsenbeschriftung sollen statt 5, 10, 15,..., 100 die Werte 50, 100, ...., 1000 stehen. Wie skaliere ich das richtig?

Das scheint ja eine einfache Multiplikation mit 10 zu sein. Die führt man am besten mit \pgfmathtruncatemacro{\ticlabel}{\i*10} aus und benutzt dann \ticlabel im Node. Ich habe die Label noch rotiert, damit sie nicht überlappen.

Vielleicht möchtest du auch lieber pgfplots verwenden und einfach die Funktion reskalieren:
