Draws layer charts.
// Delphi public function DrawChart : Boolean;
// C++ Builder public: bool DrawChart(void);
|Boolean||True if something was drawn.|
Use this method to draw layer charts. Normally this method is used by PaintChart. Using charts, we can make simple statistics by adding numbers to the charts' values property, e.g., a simple legend of population densityfor a 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.
