Hi,

How to plot the graph when width and height is fixed and average is increased more than 100.....
Please help me with this

Code: Select all

<?

$avg=10;
$max=50;
$graphValues=array($avg);
$imgWidth=100;
$imgHeight=50;

// Create image and define colors
$image=imagecreate($imgWidth, $imgHeight);
$colorWhite=imagecolorallocate($image, 0, 255, 255);
$colorGrey=imagecolorallocate($image, 192, 192, 192);
$colorBlue=imagecolorallocate($image, 0, 0, 255);
$colorred=imagecolorallocate($image, 255, 0, 0);

imagefill($image, 0, 0, $colorGrey);

for ($i=1; $i<2; $i++){
imageline($image, $i*50, 0, $i*50, 100, $colorGrey);
imagefilledrectangle($image, 0 , 0, $graphValues[0],$max,$colorred);
}


// Output graph and clear image from memory
imagepng($image);
imagedestroy($image);

?>
