Details

The PlotView 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.
