I do something similar with the gd library. I have one file which generates an x-y scatterplot and sends it to the browser, graph.php3. Then I reference graph.php3 directly from the page where I want to display it. //*************************** start graph.php3 ************************************* // initialize the graph init_graph ($scale); // run query $sql = "select x,y from foo"; $rs1 = pg_exec($conn,$sql); for ($row1 = 0; $row1 < $numrecs; $row1++) { // fill array with results $rc[0]["x"] & $rc[0]["y"] }; if ($numrecs > 0) { drawseries ($rc,$seriesclr); }; drawlabels ("Time","Value","$cmd"); // send the image header("content-type: image/gif"); ImageGif($gif); //*************************** end graph.php3 ************************************* //*************************** start mypage.php3 ************************************* $qs = "?" . $MyQueryString; $graph = "graph.php3" . $qs; print ("<IMG SRC=\"" . $graph . "\">\n"); //*************************** end mypage.php3 ************************************* I don't know if this will work with GnuPlot, but I have been planning to try it sometime soon. Please let me know if you get it to work. Hope this helps, Joe
