Inherits from
- AbstractDataSource: enthought.chaco.abstract_data_source.AbstractDataSource
Attributes
- index_dimension
The dimensionality of the indices into this data source (overrides AbstractDataSource).
index_dimension = Constant('image')
- sort_order
The sort order of the data (overrides AbstractDataSource). There is no overall sort order on 2-D data, but for gridded 2-D data, each axis can have a sort order.
sort_order = Tuple(SortOrderTrait, SortOrderTrait)
- value_dimension
The dimensionality of the value at each index point (overrides AbstractDataSource).
value_dimension = Constant('scalar')

Methods
- __init__(self, xdata = array([ ]), ydata = array([ ]), sort_order = ('none', 'none'), **kwargs)
- get_bounds(self)
get_bounds() -> ((LLx, LLy), (URx, URy))
Implements AbstractDataSource. Returns two 2-D points, min and max, that represent the bounding corners of a rectangle enclosing the data set. Note that these values are not view-dependent, but represent intrinsic properties of the DataSource.
If data axis is the empty set, then the min and max valuess are 0.0.
- get_data(self)
get_data() -> (xdata, ydata)
Implements AbstractDataSource. Because this class uses structured (gridded) data, this method returns the pair of data axes, instead of, for example, a full mesh-grid. This behavious differs from other data sources.
- set_data(self, xdata, ydata, sort_order = None)
Sets the data, and optionally the sort order, for this data source.
Parameters
- xdata, ydata : array
- The data to use.
- sort_order : SortOrderTrait
- The sort order of the data
