float FixedAspect
The fixed aspect ratio, if DrawAreaResizeBehavior is FixedAspect.
vtkTuple< vtkAxis *, 4 > Axes
vtkAxis objects that surround the draw area, indexed by vtkAxis::Location.
bool FillViewport
If true, Geometry is set to (0, 0, vpSize[0], vpSize[1]) at the start of each Paint call.
vtkRecti DrawAreaGeometry
The rect defining the pixel location and size of the clipped and transformed area inside the axes.
virtual const Margins & GetFixedMargins()
The left, right, bottom, and top margins for the draw area, if DrawAreaResizeBehavior is FixedMargins...
base class for items that are part of a vtkContextScene.
static vtkObject * New()
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
vtkTuple< int, 4 > Margins
Margins FixedMargins
The left, right, bottom, and top margins for the draw area, if DrawAreaResizeBehavior is FixedMargins...
Clipped, transformed area with axes for context items.
Class for drawing 2D primitives to a graphical context.
vtkNew< vtkAxis > BottomAxis
all children of this item are clipped by the specified area.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
DrawAreaResizeBehaviorType DrawAreaResizeBehavior
Controls how the draw area size is determined.
vtkNew< vtkAxis > TopAxis
vtkRecti Geometry
The rect defining the pixel location and size of the entire vtkContextArea, including axis label,...
takes care of drawing the plot grid
Location
Enumeration of the axis locations in a conventional XY chart.

virtual void ShowGridOn()
vtkNew< vtkContextTransform > Transform
The context item that clips rendered data.
vtkNew< vtkAxis > RightAxis
DrawAreaResizeBehaviorType
all children of this item are transformed by the vtkTransform2D of this item.
vtkRectd DrawAreaBounds
The data bounds of the clipped and transformed area inside of the axes.
virtual bool Paint(vtkContext2D *painter)
Paint event for the item, called whenever the item needs to be drawn.
takes care of drawing 2D axes
vtkNew< vtkPlotGrid > Grid
The vtkPlotGrid that renders a grid atop the data in the draw area.
virtual void ShowGridOff()
vtkRecti FixedRect
The fixed rect to use for the draw area, if DrawAreaResizeBehavior is FixedRect.
