Displaying 2 graphs in separated table

Php_Beginner2

Hello there, I wish to display 2 graphs (jpgraph) in 1 page but in separated table. I created a table with a column and 2 rows. I need the graph to be inside each row but when i try to preview them, it stated the png file cannot be displayed.

Here's my code:

<table width="1250" height="972" border="1">
  <tr>
    <td height="316"><?php // content="text/plain; charset=utf-8"
require_once ('jpgraph/jpgraph.php');
require_once ('jpgraph/jpgraph_bar.php');

$data1y=array(47,80,40,116);
$data2y=array(61,30,82,105);
$data3y=array(115,50,70,93);


// Create the graph. These two calls are always required
$graph = new Graph(350,200,'auto');
$graph->SetScale("textlin");

$theme_class=new UniversalTheme;
$graph->SetTheme($theme_class);

$graph->yaxis->SetTickPositions(array(0,30,60,90,120,150), array(15,45,75,105,135));
$graph->SetBox(false);

$graph->ygrid->SetFill(false);
$graph->xaxis->SetTickLabels(array('A','B','C','D'));
$graph->yaxis->HideLine(false);
$graph->yaxis->HideTicks(false,false);

// Create the bar plots
$b1plot = new BarPlot($data1y);
$b2plot = new BarPlot($data2y);
$b3plot = new BarPlot($data3y);

// Create the grouped bar plot
$gbplot = new GroupBarPlot(array($b1plot,$b2plot,$b3plot));
// ...and add it to the graPH
$graph->Add($gbplot);


$b1plot->SetColor("white");
$b1plot->SetFillColor("#cc1111");

$b2plot->SetColor("white");
$b2plot->SetFillColor("#11cccc");

$b3plot->SetColor("white");
$b3plot->SetFillColor("#1111cc");

$graph->title->Set("Bar Plots");

// Display the graph
$graph->Stroke();
?></td>
  </tr>
  <tr>
    <td height="316"><?php // content="text/plain; charset=utf-8"
require_once ('jpgraph/jpgraph.php');
require_once ('jpgraph/jpgraph_bar.php');

$datay=array(62,105,85,50);


// Create the graph. These two calls are always required
$graph = new Graph(350,220,'auto');
$graph->SetScale("textlin");

//$theme_class="DefaultTheme";
//$graph->SetTheme(new $theme_class());

// set major and minor tick positions manually
$graph->yaxis->SetTickPositions(array(0,30,60,90,120,150), array(15,45,75,105,135));
$graph->SetBox(false);

//$graph->ygrid->SetColor('gray');
$graph->ygrid->SetFill(false);
$graph->xaxis->SetTickLabels(array('A','B','C','D'));
$graph->yaxis->HideLine(false);
$graph->yaxis->HideTicks(false,false);

// Create the bar plots
$b1plot = new BarPlot($datay);

// ...and add it to the graPH
$graph->Add($b1plot);


$b1plot->SetColor("white");
$b1plot->SetFillGradient("#4B0082","white",GRAD_LEFT_REFLECTION);
$b1plot->SetWidth(45);
$graph->title->Set("Bar Gradient(Left reflection)");

// Display the graph
$graph->Stroke();
?></td>
  </tr>
</table>

Please advise. Thank you.

Accord to JPGraph's documentation all the stroke method does is returns a GD Lib image handle. It does not generate and output an HTML <img> tag with a URL to some PNG file that it has created and saved somewhere, which is what you appear to be expecting it to do.
