NAME

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

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=...]]

set colormap to draw tone/contour.

--itr [1-4,5-7,10-15,20-23,30-33]:

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

--similar [simfac,vxoff,vyoff]:

(for 5<=itr<=7) set similarity parameters which are fed in DCL.grssim.

set title of figure

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

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

--operation <math_func>:

operation of the specified math function on the data. <math_func> should be a math function with one argument such as log10, sqrt, sin, etc.

LINE/MARK OPTIONS

--line:

make line plot forced. (about first 1D)

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

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.

--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

EXAMPLES

For a single GPhys variable,

% gpview data.nc@temp

% gpview --nocont data.nc@temp,lon=130:150,lat=0    
% gpview --noshade data.nc@temp,lon=130:150,lat=0    
% gpview --mean lon data.nc@temp,lon=130:150,lat=0
