Hello, I hope you can help me. The Jpgraph forum seems to be pretty uneventful with participation. I am trying to pass arrays through the image tag to populate my variables for my graph. I keep getting an error that there is no input. Do you have any suggestions? I would greatly appreciate it! I have been trying to figure this out for several hours. Below is my code: I need some help with finding a solution. For some reason my graph is not showing up when it evident that my arrays are being passed. When I use: echo "TEST DATA PRINT"; print_r($datay,false); ------------------- I keep getting the error: Empty input data array specified for plot. ----------------------- My php script is as follows: ----------------------- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";> <html xmlns="http://www.w3.org/1999/xhtml";> <head> <title>KCRF Dashboard</title> <?php ini_set('display_errors', 1); error_reporting(E_ALL); $term=$_POST['term']; $term2=$_POST['term2']; $term3=$_POST['term3']; //include ('err_reporting.php'); require ('PHP_Scripts/config.php'); require_once ('jpgraph/jpgraph.php'); require_once ('jpgraph/jpgraph_line.php'); $sql = ("SELECT * FROM evdobanding WHERE Market like '%$term' and Cell_Sect = '$term2' and Date = '$term3' ORDER BY distance asc"); $result = mysql_query($sql); while($row = mysql_fetch_array($result)) { $datay[] = $row["MBusage"]; $datax[] = $row["Distance"]; } echo "TEST DATA PRINT"; print_r($datay,false); ?> <style type="text/css"> <!-- #navbar ul { margin: 0; padding: 5px; list-style-type: none; text-align: center; background-color: #000; } #navbar ul li { display: inline; } #navbar ul li a { text-decoration: none; padding: .2em 1em; color: #fff; background-color: #000; } #navbar ul li a:hover { color: #000; background-color: #fff; } --> </style> </head> <fieldset style="border: 1px ridge limegreen; color: limegreen;"> <legend style="color: #000; font-family: verdana; font-size: 14pt;">EVDO PCMD BANDING</legend> <body> <div id="navbar"> <ul> <li><a href="index.php">Home</a></li> <li><a href="dd3.php">EVDO PCMD KPI</a></li> <li><a href="banding.php">EVDO Distance Banding</a></li> <li><a href="test.php">TEST_BANDING</a></li> <li><a href="">LinkHere</a></li> </ul> </div> </fieldset> <?php echo "You Selected the following:<br>Market = $term <br>Cell_Sector = $term2<br>Timestamp = $term3<br>"; ?> <img src="bandingGraph.php?$datax=$row["Distance"]&$datay=$row["MBusage"];"> // I think this is where I am having issues. </body> </html> --------------------------- My graph script is: <?php // content="text/plain; charset=utf-8" require_once ('jpgraph/jpgraph.php'); require_once ('jpgraph/jpgraph_line.php'); // Create the graph. $graph = new Graph(1024,450,"auto"); $graph->SetScale("textlin"); $graph->SetShadow(); // Slightly adjust the legend from it's default position $graph->legend->Pos(0.03,0.5,"right","center"); $graph->legend->SetFont(FF_FONT1,FS_BOLD); //Setup X-scale $graph->xaxis->SetTextTickInterval(10); $graph->xaxis->SetTickLabels($datax); //$graph->xtick_factor = 1; $graph->xaxis->SetLabelAngle(30); // Create the linear plot $lineplot= new LinePlot($datay); $p1 = new LinePlot($datay); $p1->mark->SetType(MARK_DIAMOND); $p1->mark->SetFillColor("blue"); $p1->mark->SetWidth(; $p1->SetColor("blue"); $p1->SetCenter(); $p1->SetLegend("EVDO F1 Carrier"); $graph->Add($p1); // Add the plot to the graph $graph->Add($lineplot); // Setup margin and titles $graph->img->SetMargin(40,40,50,60); $graph->title->SetMargin(10); $graph->title->Set("Distance in MIles"); $graph->title->SetFont(FF_VERDANA,FS_BOLD,12); // set margin color $graph->SetMarginColor('#dcfade'); // Use built in font $graph->title->SetFont(FF_ARIAL,FS_NORMAL,14); $graph->ygrid->SetFill(true,'#EFEFEF@xxx','#e5e5e5@xxx'); $graph->xgrid->Show(); $graph->SetBackgroundImageMix(15); $graph->legend->Pos(0.02,0.03,"right","top"); $graph->legend->SetFont(FF_FONT1,FS_BOLD); $graph->xaxis->title->Set("Miles"); $graph->yaxis->title->Set("MBusage"); $graph->SetAlphaBlending(); // Display the graph $graph->Stroke(); ?> Thank you, Chris -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
