Method summary

• __init__(self, data = None, **traits)
• default_traits_view(self)
• map_data(self, low_xy, high_xy = None)
• map_screen(self, index, value, index_offset = 0.0, value_offset = 0.0, xy = False)
• map_xy(self, x, y)
• unselect(self)
• values_at(self, x, y)

Methods

• __init__(self, data = None, **traits)
• default_traits_view(self)

  Return the default traits view/name.

• map_data(self, low_xy, high_xy = None)

  map_data( low_xy, high_xy = None) -> [(i_low, j_low), (i_high, j_high)]

  Maps an (x,y) coordinate in data space to the closest range of integer indices into the index arrays. If a "high" value is given, then the index range returned represents the bounding coordinates in integer index space of the rectangular region in data space between low_xy and high_xy.

• map_screen(self, index, value, index_offset = 0.0, value_offset = 0.0, xy = False)
• map_xy(self, x, y)

  Maps the specified x and y coordinates from window space into data space. This differs from PlotValue.map_xy() in that the "y" argument is not optional.

• unselect(self)

  Deselect any current range selection

• values_at(self, x, y)

  Returns the list of PlotValue objects whose representation intersects a specified (x,y) point. For now, hardcode this to return just [self].
