QGraphicsView with special functionality
for plotting statistical graphics.qplotView(scene, parent, rescale=c("geometry", "transform", "none"), opengl=TRUE)QGraphicsSceneQObject, usually a
QWidget to contain the viewTRUE, use OpenGL, otherwise the software driverPlotView objectPlotView class extends QGraphicsView to add two
new features, from the user perspective. First, it automates
rescaling when the widget is resized. There are three rescale
modes: geometry, transform and none:[object Object],[object Object],[object Object]
The other feature is the overlay scene: a separate scene that is
fixed to the geometry of the viewport. It is always shown over the
primary scene and it is stationary across transformations
and scrolling of the viewport. This is useful for overlaying
guides on a plot in a fixed position, like the axes in GGobi. Call
the overlay method on a plot view instance to obtain the
overlay scene and manipulate it directly.
