class documentation

class CoordinateSystem(AbstractCairoDrawer):

Known subclasses: igraph.drawing.coord.DescartesCoordinateSystem

View In Hierarchy

Class implementing a coordinate system object.

Coordinate system objects are used when drawing plots which 2D or 3D coordinate system axes. This is an abstract class which must be extended in order to use it. In general, you'll only need the documentation of this class if you intend to implement an own coordinate system not present in igraph yet.

Method __init__ Initializes the coordinate system.
Method draw Draws the coordinate system.
Method local_to_context Converts local coordinates to the context coordinate system (given by the bounding box).

Inherited from AbstractCairoDrawer:

Method bbox.setter Sets the bounding box of the drawing area where this drawer will draw.
Instance Variable context Undocumented
Property bbox The bounding box of the drawing area where this drawer will draw.
Method _mark_point Marks the given point with a small circle on the canvas. Used primarily for debugging purposes.
Instance Variable _bbox Undocumented
def __init__(self, context, bbox):
overrides igraph.drawing.baseclasses.AbstractCairoDrawer.__init__
overridden in igraph.drawing.coord.DescartesCoordinateSystem

Initializes the coordinate system.

Parameters
contextthe context on which the coordinate system will be drawn.
bboxthe bounding box that will contain the coordinate system.
def draw(self):
overrides igraph.drawing.baseclasses.AbstractCairoDrawer.draw
overridden in igraph.drawing.coord.DescartesCoordinateSystem

Draws the coordinate system.

This method must be overridden in derived classes.

def local_to_context(self, x, y):
overridden in igraph.drawing.coord.DescartesCoordinateSystem

Converts local coordinates to the context coordinate system (given by the bounding box).

This method must be overridden in derived classes.
