I want to create graph using jpgraph. On my personal pc i configure apache, php, mysql, jpgraph, make changes to php.ini and can also view graph but problem is i have taken space for my website and i want to show graph on my website and i don't know how to check whether jpgraph support is already there or not (GD library support is available)

I upload some of jpgraph phps and jpgraph-config.inc and arialbd.ttf font and check trybar.php (which creates bar graph working perfectly on my personal pc) it shows me an error
"./fonts/arialbd.ttf is readable or not available" I also set
DEFINE("TTF_DIR","./fonts/");     in jpgraph-config.inc

Can anyone tell me what is the problem.

Hi aynsoft

You cannot open the font to create your image? Is your font path correct? And what OS are you running? Does that JPGRAPH need GD2?
First try this to see if you got FreeType support (for fonts) installed on the server. To check if you got FreeType support use something like this:

<?
$info = gd_info();
$values = array_values($info);
$keys = array_keys($info);

$count = count($info);
$i = 0;

while ($i < $count)
{
      echo "<b>".$keys[$i]."</b>";
      echo "<br>";
      echo $values[$i];
      echo "<br><br>";
      ++$i;
}
?>

Let me know...

Is the directory path correct?

./fonts/ is from the current directory

ie. the folder called fonts that resides in the same directory as jpgraph.php

Prehaps it should be /fonts/

ie. from the root of your site instead

Maybe also try realpath("your_font_path); for your font path... to make it absolute rather than relative.

Last idea is to try

DEFINE("TTF_DIR",$_SERVER['DOCUMENT_ROOT']."/fonts/");

ensuring that the "/fonts/" part is the path to your fonts folder from the root
