For the sake of the archives, I just found out that my problem was that:
echo -e "Content-type: image/png\n\n";
...actually throws in 3 newlines, not two. (Doh!) Fixing that means I now
have a CGI that generates gnuplots from postgres entirely in the pipeline,
withouut any annoying temp files. p
Well, there is this:

I thought it was overkill for me, so I went with the gnuplot method.

Heh. Funny you should ask; I spent a fair amount of time yesterday
doing precisely this.
Here's my gnuplot file:
set terminal png small color picsize 1000 400
set style fill solid 1.0 border
set title "Concurrent listeners"
set xdata time
set xlabel "Time"
set ylabel "Cuncurrent Logged In Listen
Hi All,
Has anybody tried using gnuplot to plot results from queries; there
are some suggestions given in PostgreSQL Developer's Handbook but i
have not any luck so far!
Any pointers as how to send results from queries straight to a simple
plotting utility (ex:gnuplot)!
Thanks,
