DETAILS

The controls let you set the range visible for the - plane as well as the height of the axis.
The "n-k plane plot range" slider lets you expand to . Both are expanded or contracted together.
The "z axis plot range" slider lets you expand to . As the range can be adjusted by eight orders of magnitude, it is often easier to open the control and type in the desired value.
