#### `plgzax`: Get z axis parameters

`plgzax (` | p_digmax,
| p_digits`)`;

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

`p_digmax` (``PLINT_NC_SCALAR``, output)

  Returned value of the maximum number of digits for the z axis. If nonzero, the printed label has been switched to a floating-point representation when the number of digits exceeds this value.

`p_digits` (``PLINT_NC_SCALAR``, output)

  Returned value of the actual number of digits for the numeric labels (z axis) from the last plot.

Redacted form: `plgzax(p_digmax, p_digits)`

This function is used in example 31.
