[Scilab-users] Colorbar_same color code, different graphs

[Peter Ridder]

Hallo Larissa

Mikes Vorschlag ist auch bei einem großen Datenbereich gut.
Brauchst Du in Deinen Darstellungen unbedingt die absoluten Größen?
Falls nicht, normiere die Werte und nimm die künstlichen Punkte
jeweils deutlich außerhalb des dann vorliegenden x% - 100% Intervalls.
Zu Gedränge kommt es trotzdem
