solution:
I forgot to open port 80 in firewall

[root@aaa var]# /sbin/service iptables stop

open port 80:
[root@localhost ~]# vim /etc/sysconfig/iptables
# add this line
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

[root@aaa var]# /sbin/service iptables start

jpgraph: The function imageantialias() is not available

error message:

Fatal error: Call to undefined function imageantialias() in /var/www/vhosts/bar.php on line 13

The function imageantialias() is not available in your php installation. Use the GD version that comes with PHP and not the standalone version.

SOLUTION:
Open the file jpgraph.x.x.x/src/gd_image.inc.php, find the function SetAntiAliasing and comment this line (about line 110 in the version jpgraph-3.5.0b1):

else {
//JpGraphError::RaiseL(25128);//('The function imageantialias() is not available in your PHP installation. Use the GD version that comes with PHP and not the standalone version.')
