axescolor=black color of axes
gridcolor=black color of grid
axeswidth=1 width (in points) of axes

gridwidth=axeswidth width (in points) of grid lines
style=seismic normal (axis 1 horizontal, axis 2 vertical) or
seismic (axis 1 vertical, axis 2 horizontal)
legend=0 =1 display the color scale
if ==1, resize xbox,ybox,width,height
lstyle=vertleft Vertical, axis label on left side
=vertright (Vertical, axis label on right side)
=horibottom (Horizontal, axis label on bottom)

legendfont=times_roman10 font name for title
following are defaults for lstyle=0. They are changed for other lstyles
lwidth=1.2 colorscale (legend) width in inches
lheight=height/3 colorscale (legend) height in inches
lx=1.0 colorscale (legend) x-position in inches
ly=(height-lheight)/2+xybox colorscale (legend) y-position in pixels
lbeg= lmin or wclip-5*perc value at which legend axis begins
lend= lmax or bclip+5*perc value at which legend axis ends
ldnum=0.0 numbered tic interval on legend axis (0.0 for automatic)

curve=curve1,curve2,... file(s) containing points to draw curve(s)
npair=n1,n2,n2,... number(s) of pairs in each file
curvecolor=black,.. color of curve(s)
curvewidth=axeswidth width (in points) of curve(s)

NOTES:
Currently, the curve file must have the number of points specified
at the top of the file. This file is an ascii file with the points
specified as (x1,x2) pairs, one pair to a line. A "vector" of curve
files and curve colors may be specified as curvefile=file1,file2,etc.
and curvecolor=color1,color2,etc, and the number of pairs of values
in each file as npair=npair1,npair2,... .

All color specifications may also be made in X Window style Hex format
example: axescolor=#255
