draw lines through tracking dot

[Stephen R McMillan]

Hi Daniel,

According to your script, the point x2 y2 is not defined. Perhaps you had
intended instead:

' draw line 'x0' 'y0' 'x1' 'y1

...which should draw a line segment connecting your two tracking dots.

Good luck--
Stephen McMillan

Hello everyone,
can anyone help me with this script? This script
gives a nice picture of the hurricane track of
FLOYD1999....It displays the tracking dots
nicely...but how do you show the LINES going through
the tracking dot?????  This is what I am having
problem with...here is the script

filnam='/home2/fritz/script/Floyd.dat'

'draw map'

while (1)
res = read(filnam)
rc = sublin(res,1)

if (rc > 0)
* Check if there is problem reading
if (rc = 2)
say 'EOF - Finished reading 'filnam
res = close(filnam)
break
else
say rc ' Error while reading 'filnam
res = close(filnam)
break
endif
endif

* No problems
* Step 1 - read in the position

datum = sublin(res,2)
datetime = subwrd(datum,3)
longitude = subwrd(datum,1)
latitude = subwrd(datum,2)
say longitude' 'latitude
say datetime

* Step 2 - convert lat/lon to page position
'd ugrd10m.1;vgrd10m.1;mag(ugrd10m.1,vgrd10m.1)'
'q w2xy 'longitude' 'latitude
x0 = subwrd(result,3)
y0 = subwrd(result,6)
say x0' 'y0


* Step 3 - plot the position on the page
' draw mark 2 'x0' 'y0' 0.1'
' draw mark 2 'x1' 'y1' 0.1'
' draw line 'x1' 'y1' 'x2' 'y2
endwhile

DOES ANYONE HAVE ANY SUGGESTION? :):):):):):)
