Hi,

I had a play, the maximum # points is 500,000.  If you are sampling @ 50 
sps, then this is approximately 15 hours.  For longer you could 
sub-sample.  If you averaged every 2 points into one then that would 
allow you to plot a day's worth.

Have a look at the examples on polar plots.  That may be the way to do 
heliplots...
