# plgvpd(3plplot)

Get viewport limits in normalized device coordinates

## NAME

**plgvpd** - Get viewport limits in normalized device coordinates

## SYNOPSIS

**plgvpd**(*p\_xmin*, *p\_xmax*, *p\_ymin*, *p\_ymax*)

## DESCRIPTION

Get viewport limits in normalized device coordinates.

Redacted form: General: **plgvpd(p\_xmin, p\_xmax, p\_ymin, p\_ymax)**

This function is used in example 31.

## ARGUMENTS

- *p\_xmin* (**PLFLT\_NC\_SCALAR**(3plplot), output)

  Returned value of the lower viewport limit of the normalized device coordinate in x.

- *p\_xmax* (**PLFLT\_NC\_SCALAR**(3plplot), output)

  Returned value of the upper viewport limit of the normalized device coordinate in x.

- *p\_ymin* (**PLFLT\_NC\_SCALAR**(3plplot), output)

  Returned value of the lower viewport limit of the normalized device coordinate in y.

- *p\_ymax* (**PLFLT\_NC\_SCALAR**(3plplot), output)
