Description:
 def datacursor(artists=None, axes=None, **kwargs):
 """ Create an interactive data cursor for the specified artists or specified axes. The data cursor displays information about a selected artist in a "popup" annotation box. If a specific sequence of artists is given, only the specified artists will be interactively selectable. Otherwise, all manually-plotted artists in *axes* will be used (*axes* defaults to all axes in all figures). Parameters artists : a matplotlib artist or sequence of artists, optional The artists to make selectable and display information for. If this is not specified, then all manually plotted artists in `axes` will be used. axes : a matplotlib axes of sequence of axes, optional The axes to selected artists from if a sequence of artists is not specified. If `axes` is not specified, then all available axes in all figures will be used. tolerance : number, optional The radius (in points) that the mouse click must be within to select the artist. Default: 5 points. formatter : callable, optional A function that accepts arbitrary kwargs and returns a string that will be displayed with annotate. Often, it is convienent to pass in the format method of a template string, e.g. ``formatter="{label}".format``. Keyword arguments passed in to the `formatter` function: `x`, `y` : floats The x and y data coordinates of the clicked point `event` : a matplotlib ``PickEvent`` The pick event that was fired (note that the selected artist can be accessed through ``event.artist``). `label` : string or None The legend label of the selected artist. `ind` : list of ints or None If the artist has "subitems" (e.g. points in a scatter or line plot), this will be a list of the item(s) that were clicked on. If the artist does not have "subitems", this will be None. Note that this is always a list, even when a single item is selected. Some selected artists may supply additional keyword arguments that are not always present, for example: `z` : number The "z" (usually color or array) value, if present. For an ``AxesImage`` (as created by ``imshow``), this will be the uninterpolated array value at the point clicked. For a ``PathCollection`` (as created by ``scatter``) this will be the "c" value if an array was passed to "c". `i`, `j` : ints The row, column indicies of the selected point for an ``AxesImage`` (as created by ``imshow``) `s` : number The size of the selected item in a ``PathCollection`` if a size array is specified. `c` : number The array value displayed as color for a ``PathCollection`` if a "c" array is specified (identical to "z"). `point_label` : list If `point_labels` is given when the data cursor is initialized and the artist has "subitems", this will be a list of the items of `point_labels` that correspond to the selected artists. Note that this is always a list, even when a single artist is selected. `width`, `height`, `top`, `bottom` : numbers The parameters for ``Rectangle`` artists (e.g. bar plots). point_labels : sequence or dict, optional For artists with "subitems" (e.g. Line2D's), the item(s) of `point_labels` corresponding to the selected "subitems" of the artist will be passed into the formatter function as the "point_label" kwarg. If a single sequence is given, it will be used for all artists with "subitems". Alternatively, a dict of artist:sequence pairs may be given to match an artist to the correct series of point labels. display : {"one-per-axes", "single", "multiple"}, optional Controls whether more than one annotation box will be shown. Default: "one-per-axes" draggable : boolean, optional Controls whether or not the annotation box will be interactively draggable to a new location after being displayed. Defaults to False. hover : boolean, optional If True, the datacursor will "pop up" when the mouse hovers over an artist. Defaults to False. Enabling hover also sets `display="single"` and `draggable=False`. props_override : function, optional If specified, this function customizes the parameters passed into the formatter function and the x, y location that the datacursor "pop up" "points" to. This is often useful to make the annotation "point" to a specific side or corner of an artist, regardless of the position clicked. The function is passed the same kwargs as the `formatter` function and is expected to return a dict with at least the keys "x" and "y" (and probably several others). Expected call signature: `props_dict = props_override(**kwargs)` keybindings : boolean or dict, optional By default, the keys "d" and "t" will be bound to deleting/hiding all annotation boxes and toggling interactivity for datacursors, respectively. If keybindings is False, the ability to hide/toggle datacursors interactively will be disabled. Alternatively, a dict of the form {'hide':'somekey', 'toggle':'somekey'} may specified to customize the keyboard shortcuts. date_format : string, optional The strftime-style formatting string for dates. Used only if the x or y axes have been set to display dates. Defaults to "%x %X". display_button: int, optional The mouse button that will triggers displaying an annotation box. Defaults to 1, for left-clicking. (Common options are 1:left-click, 2:middle-click, 3:right-click) hide_button: int or None, optional The mouse button that triggers hiding the selected annotation box. Defaults to 3, for right-clicking. (Common options are 1:left-click, 2:middle-click, 3:right-click, None:hiding disabled) keep_inside : boolean, optional Whether or not to adjust the x,y offset to keep the text box inside the figure. This option has no effect on draggable datacursors. Defaults to True. Note: Currently disabled on OSX and NbAgg/notebook backends. **kwargs : additional keyword arguments, optional Additional keyword arguments are passed on to annotate. Returns ------- dc : A ``mpldatacursor.DataCursor`` instance """
