Re: Web graph ?????
I've a couple of tricks to generate bar charts on the fly, using GD in one
instance, and spacer images/TD cells in the other
Using GD / javascript:
graph.htm
<script language="javascript">
function VUgauge(gaugeID)
{
var n=20;
var time=new Date();
var n=time.getSeconds();
n=Math.floor((n*100)/60);
document.getElementById(gaugeID).src='makepng.php? percent='+n;
var temp=setTimeout("VUgauge('gauge1')",1000);
}
</script>
<body onLoad="VUgauge('gauge1');">
<img name="guage1" alt="bar size controlled by javascript function VUgauge">
<img src="graph.php?percent=45" alt="bar size set by percent parameter">
</body>
graph.php
<?php
// read url parameter 'percent'
$percent=$_GET["percent"];
// calculate size of bar
$x1=floor(460*($percent/100));
// build image
$im = ImageCreate(500, 50);
// set colours, first colour created is background
$black = ImageColorAllocate($im, 0, 0, 0);
$white = ImageColorAllocate($im, 255, 255, 255);
$red = ImageColorAllocate($im, 255, 0, 0);
// set up array defining vertices of hexagonal bar, width depends on
'percent' parameter
$points=array(10,25,20,45,($x1+20),45,($x1+30),25, ($x1+20),5,20,5);
// draw polygon using array 'points' and colour red
imagefilledpolygon($im,$points,6,$red);
// write text on top of bar
imagestring($im,5,20,20,$percent.'%',$white);
// send the image to the browser
header("Content-type: image/png");
ImagePNG($im);
// tidy up
ImageDestroy($im);
?>
and for TD cells
<?php
$tablewidth=500;
$value=45;
$total=200;
$cell1=$tablewidth*($value/$total);
$cell2=$tablewidth-$cell1;
echo "<tr>";
echo "<td><td width=\"".$cell1."\" bgcolor=\"#ff0000\"><img
src=\"images/spacer.gif\" width=\"".$cell1."\"></td>";
echo "<td><td width=\"".$cell2."\" bgcolor=\"#eeeeee\"><img
src=\"images/spacer.gif\" width=\"".$cell2."\"></td>";
echo "</tr>";
?>
