[gradsusr] Scatter plot

[Jeff Duda]

Ally,

The example you link to is a script that makes a scatter plot. You don't
need a script to make a scatter plot, although the scatter.gs script
probably makes a nicer looking plot than the simple way, detailed as
follows:

Without a script, you can make a scatter plot as simply as entering

set gxout scatter
d field1;field2

where field1 and field2 are arrays in your data file (you can see a list of
arrays by typing "q file" at the command prompt or by looking in your
control file). There are numerous other commands you can use to adjust the
look of the resulting plot, including set vrange/vrange2 to adjust the
x-/y-axis limits, digsize to control the size of the markers, and perhaps
cmark to control the type of mark plotted.

Regarding the link, you have to download the script code on that website.
Then, once grads is running, you need to type "run" before the script name
and arguments. Also, make sure to include the full pathname of the script
code unless you have set the environmental variable GASCRP to the location
of your script code. Then you don't have to include the full path.

Good luck.
