I have this piece of code running on a machine several times a day, about 1
hour interval

goptions reset=global xpixels=2000 ypixels=1500
gfsname=gout device=png htext=2 gunit=pct;

filename gout "<server address here>" ;
pattern value=me color=grey repeat=50;

proc gmap data=map map=map; id state;
choro state / anno=dot discrete nolegend;
run;

what is strange is that at times, usually late afternoons when there are
lots of datapoints mapped into the map (as colored dots), the map rotates
itself into an angle, so instead of a flat US Map, it is now suddenly
written at a 45 degree angle, with florida on it's side as opposed to
north-south orientation and california-oregon is at the top of the map
(because it's mostly sideways)

most of the time, it writes a normal map that is oriented straight but at
the end of the day, sometime around 21:00 or later, I get nothing but angled
maps

why might this be happening ?

Nina,

First, I don't know. Given that it start happening in the late afternoon,
is there a chance that late afternoon is the first time in the day that you
are adding points from Hawaii and the Virgin Islands?

Art,

I only display the continental USA map so unless the nondisplayed coordinates cause
this, I just don't understand why or how since they are outside the map range

Very strange to see a US map rotated sideways at random times.
