Hey Stan:
None of the other php/gd scripts work either. I have just started working
with this so at this point all I'm doing is tinkering with a bunch of
examples .
Here's one CODE example, and it gets called from <img src="bargraph.php">
in a html page.
<?php
// graph parameters
$graphwidth = 400;
$graphHeight = 200;
$graphscale = 2;
$graphfont = 5;
$graphdata =
Array("beef"=>"99","pork"=>"75","chicken"=>"15","lamb"=>"66","fish"=>"22");
$image = imagecreate($graphwidth,$graphheight) ;
imageantialias($image,true);
$colorbody = imagecolorallocate($image,255,255,255);
$colorgrid = imagecolorallocate($image,255,0,0);
$colorbar = imagecolorallocate($image,0,255,0);
$colortext = imagecolorallocate($image,0,0,255);
imagefill($image,0,0,$colorbody);
$gridlabelwidth = imagefontwidth($graphfont)*3+1;
imageline($image,$gridlabelwidth,0,$gridlabelwidth,$graphheight -
1,$colorgrid);
$styledashed =
array_merge(array_fill(0,4,$colorgrid),array_fill(0,4,IMG_COLOR_TRANSPARENT));
imagesetstyle($image,$styledashed);
for($index = 0;$index < $graphheight;$index += $graphheight/10)
{
imageline($image,0,$index,$graphwidth -
1;$index,IMG_COLOR_STYLED);
imagestring($image,$graphfont,0,$index,round(($graphheight -
$index)/$graphscale),$colortext);
}
imageline($image,0,$graphheight - 1,$graphwidth - 1,$graphheight -
1,$colorgrid);
$barwidth = (($graphwidth-$graphlabelwidth)/count($graphdata)) -
10;
$column = 0;
foreach($graphdata as $label=>$value)
{
$bartopx = $gridlabelwidth + (($column+1) + 10) + ($column
* $barwidth);
$barbottomx = $bartopx + $barwidth;
$barbottomy = $graphheight - 1;
$bartopy = $barbottomy - ($value * $graphscale);
imagefilledrectangle($image,$bartopx,$bartopy,$barbottomx,$barbottomy,$colorbar);
$labelx = $bartopx + (($barbottomx - $bartopx)/2) -
(imagefontheight($graphfont)/2);
$labely = $barbottomy - 10;
imagestringup($image,$graphfont,$labelx,$labely,"$label:
$value",$colortext);
$column++;
}
//output image
header("Content-Type: image/png");
Imagepng($image)
ImageDestroy($image);
?>
