As a minor point, to save a little PHP face here, the code you posted above could be expressed in PHP as:


$params .= 'rows=" . count($value) . '&cols=' . count($value[0]) . '&';
for ($r=0; $r $params .= "r$r" . join(';',$value[$r]) . '&';
}


Which is not all that different than the Perl.


But as to the more important point of the liabilities of graphing in SWF, could some of the problems be solved with Flash Remoting?


That is, instead of passing all the data as URL parameters, you pass a URL to the SWF app and then have it retrieve the data. You can send arbitrary amounts of data that way.


You still have to deal with the data protection issues, but it seems like that'd be a problem in any client-side visualization app.

    Yeah, I knew there was a cleaner way to express it (we should send those guys a freebie of PHP Cookbook :-). I'd thought about turning it into an XML service, but the big problem is still data protection (which, as you say, is a problem for any client-size graphing app).

    I'm back to looking at server-side charting software. I wish there were a Perl XS wrapper to Ploticus, and may eventually wish my way into a text editor to make it so.

    Thanks! --Nat

    Argh. The < in my PHP gets eaten. View Source to see my handiwork. :(
