This command is obsolete beginning with grads version 2.1. It has been replaced by
enable print fname
This command opens the output file
fname that will contain the instructions in grads metacode format to create a hardcopy of the graphical display. Any existing contents of
fname will be lost. The output file
fname is referred to as a grads metafile.
eloop function is similar to the
tloop function. When displaying a grads expression (
expr) with the E (Ensemble) dimension varying, the
eloop function will evaluate the
exprwith each designated ensemble member fixed, then reassemble the grids to obtain a final result that is E-varying. The
eloop function is provided as a way to obtain E-varying results from functions or expressions that are unable to operate when E is a varying dimension.
query command allows the user to get information about a variety of aspects of the current grads session. Configuration, plot characteristics, graphics specifics, and file structure are some examples. The use of
query pos combined with the coordinate transformations is the basis of many interactive applications with buttons and drop menus. The
query command may be shortened to simply
q. The syntax is:
set cterp on|off
Turns spline smoothing on or off. "Sticks" until reset. Shaded contours are drawn without spline fitting, so to insure an exact match when overlaying contour lines and shaded contours of the same field, specify
cterp as off. You can still use the
csmooth option, which affects both contour lines and shaded contours.
