[rrd-users] Creating dynamic graphs in HTML

I'm trying to create inline graphs using rrdtool 1.2.23 (RRDs).

I have something like this in a perl script:

print $cgi->header(-type=>'image/png');
RRDs::graph ("-","-s","-1week","-a","PNG","--width","600","--

If I substitute "-" with a file name, it produces a file that I can
view, but when I try to do this inline I get an error saying there are
errors in the image.

I used to do this with gif format in 1.0.49 and it worked just fine.

Any ideas?
