# plsxax(3plplot)

Set x axis parameters

## NAME

**plsxax** - Set x axis parameters

## SYNOPSIS

**plsxax**(*digmax*, *digits*)

## DESCRIPTION

Sets values of the *digmax* and *digits* flags for the x axis.  See the PLplot documentation for more information.

Redacted form: **plsxax(digmax, digits)**

This function is used in example 31.

## ARGUMENTS

- *digmax* (**PLINT**(3plplot), input)

  Variable to set the maximum number of digits for the x axis.  If nonzero, the printed label will be switched to a floating-point representation when the number of digits exceeds *digmax*.

- *digits* (**PLINT**(3plplot), input)

  Field digits value.  Currently, changing its value here has no effect since it is set only by [**plbox**(3plplot)](/plbox/3plplot.md) or [**plbox3**(3plplot)](/plbox3/3plplot.md).  However, the user may obtain its value after a call to either of these functions by calling [**plgxax**(3plplot)](/plgxax/3plplot.md).
