Class DiagramView

java.lang.Object
  corelib.services.web.components.WebComponent
      corelib.services.web.components.diagrams.DiagramView

Direct Known Subclasses:

CurveView, HistogramView, PieView

public abstract class DiagramView
extends WebComponent

This base class defines common behaviors for views used on a diagram component. A view draws the data stored into a diagram model.

You can use a derived view class (corelib.services.web.components.diagrams.DiagramView, corelib.services.web.components.diagrams.CurveView or corelib.services.web.components.diagrams.PieView. You can also derives your specific view: in this case, the raw behavior must be implemented in Javascript (see JWT diagram architecture for more informations).
