### `plszax`: Set z axis parameters

`plszax` (digmax, digits);

Identical to `plsxax`, except that arguments are flags for z axis. See the description of `plsxax` for more detail.

`digmax` (`PLINT`, input) Variable to set the maximum number of digits for the z axis. If nonzero, the printed label will be switched to a floating point representation when the number of digits exceeds ``digmax``. `digits` (`PLINT`, input) Field digits value. Currently, changing its value here has no effect since it is set only by `plbox` or `plbox3`. However, the user may obtain its value after a call to either of these functions by calling `plgzax`.
