As I explained, as I write this, k0ani-11 was last recieved on the APRS IS 1393
hours ago! So last=48 returns no points. This cgi is still incomplete, when I
have a chance rather than returning nothing it will return an image containing
an error message like this one:

http://findu.com/cgi-bin/radar-find.cgi?call=k0ani-11
 
but the fact is, if there is no data, there can be no graph, and any search on
k0ani-11 where last is less than 1393 returns no data. By tomorrow, last will
need to be 1417 to show a graph. As I stated, I think somehow you got the
mistaken impression that last was relative to the last time the station
transmitted, but like all cgis on findU, last is relative to the time the
database is searched.
