PLOT problem

[Guillaume Descamps <gdescamp@xxxxxxxxxxxxx>]

About PLOT problem in my last question
../fu_2001/msg00400.html

It seems to be a precision problem. 

For coordinates in lat-long like
-72.59805 45.67111 50.3

if I specify 2 decimals precision PPL XFOR (f10.2), all my points have an
error of +0.05 in latitude.

with 3 decimals PPL XFOR (f10.3), everything is o.k., my coordinates are
plotted at the correct positions.


I solved my problem but I still don't understand +0.05 ???


Command exemple:
SET DATA/EZ/VAR="longitude,latitude,value" "/tmp/my_data.txt"
PLOT/VS/SYMBOL=17/TITLE="Localisation" longitude,latitude
PPL XFOR (f10.3)
PPL YFOR (f10.3)
PPL PLOT
