Hello,

I upgraded the PHP version from 7.4.33 to PHP 8.2.12

I get the message error undefined constant "IMG_PNG" \jpgraph\src\jpgraph_errhandler.inc.php in line 282

Previously I was running jpgraph v4.4.0 with PHP7.4.33

I upgraded jpgraph v4.4.0 to jpgraph v4.4.2

Is it OK?

Is this version compatible with PHP 8.2.12?

What can I do to solve the problem?

Thanks for your answer.

There is jpgraph version compatible with latest PHP versions: https://packagist.org/packages/mitoteam/jpgraph

Unfortunately original JpGraph library is not compatible with php8.2 (even if they say so on official website).
