[gradsusr] Plotting points and lines in GrADS

[Matt Bunkers - WFO UNR]

Hi Jason,

To draw lines all you need to use is this:

'set line color style thickness'
'draw line x1 y1 x2 y2'

The x,y points are in inches from the upper left of the display.  Just play
around with them to get the location you want.

You can plot a point using font 3 and the number 2 (which will make a
bullet point).  For example,

'set string 1 c 6 0'
'set strsiz 0.13 0.13'
'set font 3'
'draw string '4.25' '5.5' 2'

will place a point roughly in the middle of the display.
