quick viewer for the values of a variable specified by
a gtool4-type URL.
(1) for 1-dimensional variable, make line plot.
(2) for 2-dimensional variable, make contour/tone plot.
(3) for 3/more-dimensional variable, make contour/tone
plot, select first 2D. possible to make animation.
The first command form is
% gpview [options] gturl1 gturl2 gturl3 ...
where the format of the gturl is
path@varname[,dimname=pos1[:pos2[:thinning_intv]][,dimname=...]]
The second commnad form is
% gpview --var url [options] gtfile1 gtfile2 ...
where the format of the url is
varname[,dimname=pos1[:pos2[:thinning_intv]][,dimname=...]]
if you want to know more description, please read

--help : print this message.
--var url : set the variable name and slicing parameters.
--wsn [1-4] : set work staion number. each number represent
output device:
1 : X window.
2 : PS file. (named dcl.ps)
3 : Tcl/Tk file.
4 : GTK Windows (depend on dcl-5.3)
--itr [1-4,5-7,10-15,20-23,30-33]
1 : linear scale for x/y axis
2 : linear scale for x , log scale for y axis
3 : log scale for x , linear scale for y axis
4 : log scale for x/y axis
--similar [simfac,vxoff,vyoff]
: (for 5<=itr<=7) set similarity parameters
which are fed in DCL.grssim.
--map_axis [uxc,uyc,rot]
: (for 10<=itr<=33) set mapping parameters
which are fed in DCL.umpcnt.
--title : set title of figure
--aspect <aspect> : set aspect ratio of Viewport. default is 2.0.
--noannotate : not draw annotations.
--animate/anim <dim> : plot animation along <dim>.
<dim> must be name of dimension.
--alternate, --Ga : enable to backing store.
--nowait, --Gw : not wait for any actions if animate
--reverse, --Gr : plot animation reversible if animate
--smooth, --Gaw : equal to --anlternate && --nowait
--exch : exchange(transpose) x/y axis.
--mean <dim> : mean along axis <dim>.
--m, --map <map_type> : plot map. itr number must be set.
this option is neglect if itr number is 1-4.
abailable map type is
coast_world, border_world, plate_world, state_usa,
coast_japan, pref_japan
--line : make line plot forced. (about first 1D)
--index : set DCL line index, which set the color/thickness
of the line primitive. please see DCL documents.
--type : set line type.
--range [min:max] : set min/max value for line plot.
min or max must be set.
--overplot : set number of lines on each figure
--shade : make contour and tone plot.
--noshade : make contour plot, without tone.
--nocont : make tone plot, without contour.
--range [min:max] : set min/max value for contour/tone plot.
min or max must be set.
--crange : set min/max value for contour plot. this is more
dominant than --range
--srange : set min/max value for tone plot. this is more
dominant than --interval/int
--interval,--int [num]: set interval value for contour/tone plot.
set the number of lines if you set negative value.
--cint : set interval value for contour plot. this is more
dominant than --interval/int
--sint : set interval value for tone plot. this is more
dominant than --interval/int.
--levels : set values of contour/tone levels.
--clevels : set values of contour levels.
--slevels : set tone of contour levels.
--patterns : set each patterns for tone plot.
--nocolorbar : do not draw color bar
--nozero : do not draw zero contour
