Methods
- map_data(self, screen_pt)
Maps a screen space point (sx, sy) to the "index" space of the plot.
Returns a floating point number, not an integer index.
- map_index(self, screen_pt, threshold = 0.0, outside_returns_none = True, index_only = False)
Maps a screen space point to an index into the plot's index array(s).
Parameters
- screen_pt : (x,y)
- The screen space point to map.
- threshold : float
- Optional screen-space distance allowed between screen_pt and the plot; if non-zero, then a screen_pt within this distance is mapped to the neared plot index. (This feature is useful for sparse 2-D data.)
- outside_returns_none : Boolean
- If True, then if screen_pt is outside the range of the data, the method returns None. If False, it returns the nearest end index in such a case.
- index_only : Boolean
- If True, then this method maps based only on the index coordinate of screen_pt, and ignores the value coordinate.
Returns
An index into the plot's index array(s). Typically this index is just an integer, but if the plot has a 2-D index dimension, then this method returns a tuple of integers. If the input point cannot be mapped to an index, then None is returned.
If screen_pt corresponds to multiple indices, then only the first index is returned.
- map_screen(self, data_array)
Maps an array of data points to screen space and returns an array of screen space points.
