Draws layer charts.

// Delphi
public
  function DrawChart : Boolean;

// C++ Builder
public:
  bool DrawChart(void);

Use this method to draw layer charts. Normally used by PaintChart. Using charts we can make simple statistics adding numbers to charts values property, eg. a simple legend of population density on given area.

When using this operation, never call any function which uses FindFirst..FindNext (any function which iterates through the shapes using it - so never use inside an operation like Locate, PaintScope etc.).
