GRAPH Tutorial : Miscellaneous

You may convert gmeta files to a number of other graphic formats. For example, to convert to black-white postscript file, you can use the command:

ctrans -d ps.mono gmeta> gmeta.ps

'-d ps.color' will allow you to translate color plots. For more information, check man page on 'ictrans'.

To convert gmeta files to GIF images, a very handy tool is the ncgm2gif script

ncgm2gif -res 500x500 -nomerge gmeta

Will convert all images in gmeta to gmetaxxx.gif

If your data size is greater than 200x200x40 in i, j and k directions, you should modify two include files in the src/ directory to increase the dimensions: data.incl and scratch.incl.
 

If the input data to GRAPH is on sigma, then vertical interpolation is possible. For example, this g_plots.tbl shows how to plot sigma-level data on pressure levels for variable temperature and geopotential height, and this g_plotst.tbl shows how to plot sigma-level data on isentropic levels for PV and pressure.
