Hi,
I need some help. I need to be able to display my graph with text above and below the actual PHP graph.
http://132.156.178.22/stephweb/php/stephanie.php

I tried even printing a simple "Hello World" string, but it seems as if the script stops after the Stroke();

Is there an easy way to do this?

Can anyone help me?

Thanks,
Stephanie


My Code

<?php
include ("../jpgraph.php");
include ("../jpgraph_bar.php");

$data1y=array(12,8,19); // house
$data2y=array(8,2,11); // potential

// Create the graph. These two calls are always required
$graph = new Graph(400,300,"auto"); //(length, height)
$graph->SetScale("textlin",0,35);

$graph->yscale->ticks->Set(35,10);
$graph->yaxis->SetColor("lightblue");

$graph->SetMarginColor("lightblue");
$a = array("Heating\nConsumption","Cooling\nConsumption ","Hot Water Tank\nConsumption");

$graph->xaxis->SetLabelAlign('center');
$graph->xaxis->SetTickLabels($a);
$graph->xaxis->SetFont(FF_ARIAL);
$graph->SetShadow();
$graph->img->SetMargin(40,30,20,80);

// Create the bar plots
$b1plot = new BarPlot($data1y);
$b1plot->SetFillColor("midnightblue");
$b1plot->SetLegend("Your House");

$b2plot = new BarPlot($data2y);
$b2plot->SetFillColor("steelblue3");
$b2plot->SetLegend("Your Potential");

$gbplot = new GroupBarPlot(array($b1plot,$b2plot));
$gbplot->SetWidth(0.7);

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

$graph->title->SetFont(FF_ARIAL,FS_BOLD,20);
$graph->yaxis->title->SetFont(FF_ARIAL,FS_BOLD);
$graph->xaxis->title->SetFont(FF_ARIAL,FS_BOLD);

$graph->title->Set("Energy Consumption");
$graph->yaxis->title->Set("Energy");

// Display the graph
$graph->Stroke();

print("Hello<br>");
?>

Did you ever get an answer to this? I sure would like to know how to do this, too.

No I didn't, and I have to figure it out soon...

why don´t you try with GD?

http://es.php.net/manual/en/function.imagettftext.php

Code:

<?php
  header("Content-type: image/jpeg");
  $im = imagecreate(400, 30);
  $white = imagecolorallocate($im, 255, 255, 255);
  $black = imagecolorallocate($im, 0, 0, 0);
 
  // Replace path by your own font path
  imagettftext($im, 20, 0, 10, 20, $black, "/path/arial.ttf",
  "Testing... Omega: &amp;#937;");
  imagejpeg($im);
  imagedestroy($im);
?>

Hi Stephanie, I wonder if you ever figured it out.

As i understand it you want your image to appear on the page, and to then be able to write text on the page afterwards.

This is not possible in the way you tried as the "headers have already been sent". Basically you can't have a php page that generates a JPGraph and then add text ans stuff to that page.

A quick way around this is to have the JPGraph php code that produces your graph in one page, e.g. linegraph.php and then to have another page, e.g. index.html or index.php that calls the linegraph.php:
<td><img src="linegraph.php" name="line graph"/></td>
When the index.php page is loaded, linegraph.php will be executed and the resulting image will be displayed on the image.php page.

You are free to put allsorts on your main.php page - images, text, everything.

Let me know if this was of any use.
