The use of eval() is discouraged.

The variable $t does not seem to be defined for all execution paths leading up to this point.

        // If there is an error in the function specifcation this is the only
        // way we can discover that.
        if (empty($xa) || empty($ya)) {

The variable $xa seems to never exist and therefore empty should always be true.

The variable $ya seems to never exist and therefore empty should always be true.

            JpGraphError::RaiseL(24002);
        }
        //('FuncGenerator : Syntax error in function specification ');

        return [$xa, $ya];

The variable $xa does not seem to be defined for all execution paths leading up to this point.

The variable $ya does not seem to be defined for all execution paths leading up to this point.
