set gxout

set gxout graphics_type

Where graphics_type can be one of the following:

bar       Bar chart (The librarycontains an example scriptdemonstrating how to use gxout bar and errbar)
barb      Wind barbs
contour   Contour plot
errbar    Error bars (The librarycontains an example scriptdemonstrating how to use gxout bar and errbar)
geotiff   (2.0.a5+) Generates a GeoTIFF format data file; options specified by set geotiff
grfill    Shaded grid boxes
fgrid     Shaded grid boxes with values specified by set fgvals
fwrite    Writes data to file instead of drawing a plot; options specified by set fwrite
grid      Grid boxes with printed values
imap      (2.0.a8+) Quickly drawn shaded grid boxes. No metafile, so no hard copy; image output only with outxwd.
kml       (2.0.a5+) Generates a TIFF image file and a KML text file; options specified by set kml
line      Line Graph
linefill  Color fill between two lines
print     Generates ascii output for anything displayed; controlled by set prnopts
scatter   Generates a scatter diagram. Requires two grid expressions as arguments, separated by a semicolon. See Usage Note #2 below.
shaded    Shaded contour plot, alias for original algorithm (shade1)
shade1    (2.0.0+) Shaded contour plot, original algorithm
shade2    (2.0.0+) Shaded contour plot, new algorithm, polygons merged to be larger and fewer in number (faster to render)
shade2b   (2.0.0+) Shaded contour plot, new algorithm, polygons all on sub-grid scale (slower to render)
shp       (2.0.a9+) Generates a shapefile; options specified by set shp
stream    Wind streamlines
stat      Prints statistical output to terminal instead of drawing a plot
vector    Wind vector arrows

For station data, these additional graphics output types are also available:

findstn   Finds nearest station
model     Plots station model
stnmark   Plots a mark at station location that is colorized by data value
tserbarb  Time series of wind barbs at a point (1-D)
tserwx    Time series of weather symbols at a point (1-D)
value     Plots station values
wxsym     Plots weather symbols at station, controlled by set wxopt

Usage Notes

1. For the graphics output types vector, stream, and barb, the plotting routines need two result grids, where the first result grid is treated as the U component, and the second result grid is treated as the V component. These two result grids are provided with the display command by entering two expressions separated by a semicolon:
   display u ; v
display ave(u,t=1,t=10) ; ave(v,t=1,t=10)

2. For the graphics output types vector and stream, you can specify a third grid expression that will be used to colorize the vectors or streamlines:
   display u ; v ; mag(u,v)
display u ; v ; hcurl(u,v)
   Beginning with GrADS version 2.0.2, the graphics output type scatter will also take a third grid expression to colorize the points in the scatter diagrm.

3. To draw a 1-D time series with graphics output types vector or barb, set the dimension environment so that only time is varying, then :
   display const(u,0); u ; v

4. For the graphics output type wxsym, each value at a station location is assumed to be a wx symbol code number. To see a chart of all available wx symbols and their corresponding code numbers, run the sample script wxsym.gs.

5. The graphics output type findstn requires three arguments to be provided with the display command. The first argument is a station data expression. The 2nd and 3rd arguments are the X and Y screen coordinates of the of the desired search location. GrADS will find the station closest to the specified X and Y position, and print its stid, lon, and lat. This graphics output type should only be used when X and Y are the varying dimensions and AFTER a regular display command (that results in graphics output) is entered.

6. For the graphics output type stnmark, the size and style of the mark are controled by set digsiz and set cmark. To turn off rainbow colorizing and use a single color instead, use set ccolor color#.
