Topic: Values of y-axis can't be changed ??
When using Zoom, Kvadratisk (danish! ;-) ) it is no longer possible to change y-values for axis (in the box) - not even after returning tom Zoom, Standard, which - by the way - not allways is possible either.
But a very usefull program, which is being used i teaching math by more and more colleges i DK (så tak for det !!)
