Graphs with PHP

[Barrucadu]

This may be simple but it took me a while to figure out, you will need a 1x1 png image for your graph's background

//Sample Graph
$graph[0] = 5;
$graph[1] = 8;
$graph[2] = 1;
$graph[3] = 52;

//How much to scale the graph up (use a decimal to scale down)
$scale = 2;

//Code Starts Here
echo '<span style="font-family:\'Courier New\', Courier;">';
	
$i=1;
foreach($graph as $point){
     $point = $point * $scale;
     if($i < count($graph)){
          echo '<img style="border-top:1px solid #000000;border-left:1px solid #000000;border-bottom:1px solid #000000;" src="graph.png" height="'.$point.'" width="40px"/>';
     }else{
          echo '<img style="border:1px solid #000000;" src="graph.png" height="'.$point.'" width="40px"/>';
     }
}
	
echo '<br/>';
	
foreach($graph as $point){
     if($point <= 9){
          echo $point.'     ';
     }elseif($point <= 99){
          echo $day['income'].'    ';
     }elseif($day['income'] <= 999){
          echo $day['income'].'   ';
     }
}
echo '</span>';

Not to take anything away from you Mikor, but for those who need something a little stronger and don't know about it, there's also the dual-licenced JPGraph library which does all sorts of graphs pretty nicely.

So long as you learnt something along the way, you didn't waste any time!

JPGraph is really good: admittedly, it doesn't build the graph straight in to the HTML as yours seems to, but it does do awesome graphs into various file formats. Trust me, it's worth the time to learn!
