Hi Philipp,

I am sorry about that.  The stats were originally calculated separately.=20
  This meant the graphs were slow, two reads of the database.  So I got=20
them to calculate once and store in an external file, at the same time=20
as getting the data.  Written by the image program (perfchart.cgi), read=20
by the HTML frame to the graph (perfgraph.cgi) and displayed.

I used a 'hack', by half showing the HTML including the URL to the=20
image.  The image program would run.  Then the rest of the HTML would=20
show including the stats :)  Which I found out later didn't work using a=20
Proxy, as this fully assembles the HTML before sending to client=20
browser.  This caused long timeouts and strange errors, which I never=20
got a good fix to.

The only neat solution is to get the graph calling HTML to assemble all=20
the data in a tmp file, get the stats, then call the graph to read the=20
tmp file and display.  Which was also going to form the start of a cache=20
to speed up graph drawing by several orders.  But not got there yet :)

These will return at a later date.  If you are not using PP through a=20
proxy server, it's easy to get the stats back.  I'll email you some=20
instructions if you want.

Regards, Ben.
