You can put <img src=http://domain.com/path/to/yourscript.pl> in your

In yourscript.pl you can spit the image out to stdout by saying: 
	$graph = `rrdtool graph - <options>`.
	print "Content-type: image/png\n";
	print $graph;

Subject: [rrd-users] Possible to store graph in variable?
Hi rrd-users,

I wrote a perl-cgi script to generate graphs and html-pages on demand.
The user can choose some parameters and the graphs 
will be created and stored to disk. From disk they are inserted into

My question is now if it is possible to store a graph in a variable (or
something else)
and print it to html from there (I don't want to use rrd-cgi Module) ?
