TGIS_LayerVector.DrawChart method

DK11 for Delphi | GisLayerVector.TGIS_LayerVector.DrawChart | Constructors | Fields | Methods | Properties | Events

Draws layer charts.

Available also on: .NET | Java | ActiveX.


// Delphi
  function DrawChart : Boolean;
// C++ Builder
  bool DrawChart(void);


Type Description
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 density for 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 etc.
