ich habe folgendes Problem. Beim Erstellen eines 3D-Gitters würde ich gerne Ticks an den Achsen haben, jedoch sollen die Werte, die dort dran stehen, frei wählbar sein. Statt y=5 will ich dort beispielsweise (N+1) stehen haben. Ich weiß leider gar nicht wie das geht und in den Anleitungen habe ich dazu nichts gefunden.
(Thema auch bei TexWelt: http://texwelt.de/wissen/fragen/11421/3 ... derzeichen)
Dazu will ich noch ein Sonderzeichen (xi) sie z-Achse im Bild einfügen.
Mein Code bisher:
