gpview

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.

USAGE

% gpview [options] url
where the format of the url is

    path@varname[,dimname=pos1[:pos2[:thinning_intv]][,dimname=...]]

GLOBAL OPTIONS

--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]           : set axis scale. default is 1.
                        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

--title               : set title of figure

--aspect <aspect>     : set aspect ratio of Viewport. default is 2.0.

--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 

--smooth, --Gaw       : equal to --anlternate && --nowait

--exch                : exchange(transpose) x/y axis.

--mean <dim>          : mean along axis <dim>. 

LINE OPTIONS

--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.

CONTOUR/TONE OPTIONS

--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.
