ChartDirector constants are implemented as true PHP constants. For example, the NoValue constant is just
NoValue, not $NoValue. The '$' character is not needed.The exceptions are constants that represent arrays, like whiteOnBlackPalette. PHP does not support true constants for arrays. As a result, they can only be implemented as variables, and so require leading
'$' characters (eg. $whiteOnBlackPalette).True PHP constants have global scope by default, which means they are automatically visible inside function definitions. On the other hand, PHP variables has local scope by default. If used inside function definitions, an explicit PHP "global" statement is needed.
