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)

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