class DescartesCoordinateSystem(CoordinateSystem):

Class implementing a 2D Descartes coordinate system object.

Method	`__init__`	Initializes the coordinate system.
Method	`bbox.setter`	Sets the bounding box of the coordinate system
Method	`bounds.setter`	Sets the lower and upper bounds of the X and Y values
Method	`draw`	Draws the coordinate system.
Method	`local_to_context`	Converts local coordinates to the context coordinate system (given by the bounding box).
Property	`bbox`	Returns the bounding box of the coordinate system
Property	`bounds`	Returns the lower and upper bounds of the X and Y values
Method	`_recalc_scale_factors`	Recalculates some cached scale factors used within the class
Instance Variable	`_bbox`	Undocumented
Instance Variable	`_bounds`	Undocumented

Instance Variable	`context`	Undocumented
Method	`_mark_point`	Marks the given point with a small circle on the canvas. Used primarily for debugging purposes.

def __init__(self, context, bbox, bounds): ¶

overrides igraph.drawing.cairo.base.AbstractCairoDrawer.__init__

Initializes the coordinate system.

Parameters
context	the context on which the coordinate system will be drawn.
bbox	the bounding box that will contain the coordinate system.
bounds	minimum and maximum X and Y values in a 4-tuple.

@bbox.setter
def bbox(self, bbox): ¶

overrides igraph.drawing.cairo.base.AbstractCairoDrawer.bbox.setter

Sets the bounding box of the coordinate system

@bounds.setter
def bounds(self, bounds): ¶

Sets the lower and upper bounds of the X and Y values

def draw(self): ¶

overrides igraph.drawing.cairo.coord.CoordinateSystem.draw

Draws the coordinate system.

def local_to_context(self, x, y): ¶

overrides igraph.drawing.cairo.coord.CoordinateSystem.local_to_context

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