  bool DrawChart(void);

Result

Type Description
Boolean True, if something was drawn.

Remarks

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.).
