#### `plgxax`: Get x axis parameters

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

Returns current values of the ``p_digmax`` and ``p_digits`` flags for the x axis. ``p_digits`` is updated after the plot is drawn, so this routine should only be called after the call to `plbox` (or `plbox3`) is complete. See the section called “Annotating the Viewport” for more information.

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

  Returned value of the maximum number of digits for the x 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 (x axis) from the last plot.

Redacted form: `plgxax(p_digmax, p_digits)`

This function is used in example 31.
