Class implementing a 2D Descartes coordinate system object.

Instance Methods

[hide private]

__init__(self, context, bbox, bounds)
Initializes the coordinate system.

_get_bbox(self)

_get_bounds(self)

_recalc_scale_factors(self)

_set_bbox(self, bbox)

_set_bounds(self, bounds)

local_to_context(self, x, y)
Converts local coordinates to the context coordinate system (given by the bounding box).

plot(self)
Draws 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.

Overrides: object.__init__
