GSLIB Help Page: PROBPLT

Description:

probplt generates either a normal or a lognormal probability
plot. This plot displays all the data values on a chart that
illustrates the general distribution shape and the behavior of the
extreme values. Checking for normality or lognormality is a secondary
issue.

Parameters:

datafl: the data file in a simplified GeoEAS format.

icolvr and icolwt: column number for the variable and
the weight. If icolwt less than or equal to 0, equal weighting
is considered.

tmin and tmax: all values strictly less than tmin
and strictly greater than tmax are ignored.

outfl: file for PostScript output.

ilog: =0 then an arithmetic scaling of the variable scale
is used, =1 then a logarithmic scaling (base 10) is used.

pmin, pmax and pinc: minimum, maximum plotting limits,
and increment for the variable axis.

title: a 40character title for the top of the plot.
