Class Library

This section describes the core ChartDirector classes.

Many ChartDirector APIs accept array of numbers or strings as arguments. However, in Perl, it is impossible to use arrays as function call arguments without losing their structure. So in this documentation, all functions or methods that accept arrays actually means "array references" in Perl.

Similarly, functions or methods that return arrays actually means "array references" in Perl.

perlchartdir is the Perl module for interface with ChartDirector. It includes all ChartDirector classes, general informational functions and predefined constants.
