Re: trajectories-on-a-map plot
Hi Michael,
I don't see anything wrong with your commands. Defining an axis
as you are doing is the right thing to do for a long file. Do you
perhaps have a region set in X? Try just the grid set-up and read
and SHOW DATA in a fresh Ferret session.

Dear Ferreters!
I would like to plot trajectories (lon,lat,press) - with the pressure
height being colored - onto a map.
The file is very long with more than 50000 lines (see below)
name title I J
K L
LON LON 1:50784 ...
... ...
LAT LAT 1:50784 ...
... ...
PRESS PRESS 1:50784 ...
... ...
If I start my script
#############################################
go basemap X=110w:20e Y=20:75 20
define axis/x=1:"50784":1 xax
define grid/x=xax goon
file/column=3/var="lon,lat,press"/grid=goon CET_ATTILA_T106L19
GO polymark POLY/OVER/KEY/LEVELS="(200,1000,100)"/nolab lon+360 lat
press/100. circle 0.2
############################################
it runs, but not all lon, lat and press values are plotted onto the
map. If I type "show data",
the data looks like that:
name title I J
K L
LON LON 1:1104 ...
... ...
LAT LAT 1:1104 ...
... ...
PRESS PRESS 1:1104 ...
... ...
What has happened????? How can I plot all values onto the map???
Greetings
Michael
