set cstyle

set cstyle style

Sets the contour linestyle. style options are:

0 - no contours 
1 - solid 
2 - long dash 
3 - short dash 
4 - long dash, short dash 
5 - dotted 
6 - dot dash 
7 - dot dot dash 

set csmooth

set csmooth on|off

If on, the grid is interpolated to a finer grid using cubic interpolation before contouring. "Sticks".

Using grads Station Data

This section describes some of the grads commands and functions that are available for analyzing and displaying station data. Please refer to the companion section About Station Data for information on the structure of station data files, how to create them, and how to instruct grads to interpret them properly.

Here are some quick links for skipping through this section:

set coslat

set coslat on|off

Sets scaling of the Latitude dimension to be the cosine of latitude, producing a "crunched" effect near the poles. Will only work for 1-D plots in which Latitude (Y) is the varying dimension. Sticks until reset.

cos

cos(expr)

Takes the cosine of the expr. Values are assumed to be in radians. Works on both gridded and station data.

()tcorr

(tcorr (expr1, expr2, tdim1, tdim2

This function produces a spatial map of temporal correlation coefficients.

expr1   - a valid grads expression that varies in time
expr2   - a valid grads expression that varies in time and may also vary in X and Y
tdim1   - starting time dimension expression 
tdim2   - ending time dimension expression 

()scorr

This function calculates the spatial correlation between two variables over an X-Y domain. It returns a single number. The syntax is:

(scorr(expr1, expr2, xdim1, xdim2, ydim1, ydim2
