- AbstractMapper: enthought.chaco.abstract_mapper.AbstractMapper
Attributes
- range
The data-space bounds of the mapper.
range = Instance(DataRange2D)
- screen_bounds
Convenience property for low and high positions in one structure. Must be a tuple (x_low_pos, x_high_pos, y_low_pos, y_high_pos).
screen_bounds = Property
- stretch_data_x
Should the mapper stretch the dataspace when its screen space bounds are modified (default), or should it preserve the screen-to-data ratio and resize the data bounds? If the latter, it will only try to preserve the ratio if both screen and data space extents are non-zero.
stretch_data_x = DelegatesTo('_xmapper', prefix = 'stretch_data')
- stretch_data_y
stretch_data_y = DelegatesTo('_ymapper', prefix = 'stretch_data')
- x_high_pos
The screen space position of the upper bound of the horizontal axis.
x_high_pos = Float(1.0)
- x_low_pos
The screen space position of the lower bound of the horizontal axis.
x_low_pos = Float(0.0)
- y_high_pos
The screen space position of the upper bound of the vertical axis.
y_high_pos = Float(1.0)
- y_low_pos
The screen space position of the lower bound of the vertical axis.
y_low_pos = Float(0.0)
