mpl_interactions.interactive_hist

interactive_hist(arr, density=False, bins='auto', weights=None, ax=None, slider_formats=None, force_ipywidgets=False, play_buttons=False, play_button_pos='right', controls=None, display_controls=True, **kwargs)[source]

Control the contents of a histogram using widgets.

See https://github.com/ianhi/mpl-interactions/pull/73#issue-470638134 for a discussion of the limitations of this function. These limitations will be improved once https://github.com/matplotlib/matplotlib/pull/18275 has been merged.

Parameters

  • arr (arraylike or function) – The array or the funciton that returns an array that is to be histogrammed

  • density (bool, optional) – whether to plot as a probability density. Passed to np.histogram

  • bins (int or sequence of scalars or str, optional) – bins argument to np.histogram

  • weights (array_like, optional) – passed to np.histogram

  • ax (matplotlib axis, optional) – If None a new figure and axis will be created

  • slider_format_string (None, string, or dict) – If None a default value of decimal points will be used. For ipywidgets this uses the new f-string formatting For matplotlib widgets you need to use % style formatting. A string will be used as the default format for all values. A dictionary will allow assigning different formats to different sliders. note: For matplotlib >= 3.3 a value of None for slider_format_string will use the matplotlib ScalarFormatter object for matplotlib slider values.

  • force_ipywidgets (boolean) – If True ipywidgets will always be used, even if not using the ipympl backend. If False the function will try to detect if it is ok to use ipywidgets If ipywidgets are not used the function will fall back on matplotlib widgets

  • play_buttons (bool or dict, optional) – Whether to attach an ipywidgets.Play widget to any sliders that get created. If a boolean it will apply to all kwargs, if a dictionary you choose which sliders you want to attach play buttons too.

  • play_button_pos (str, or dict, or list(str)) – ‘left’ or ‘right’. Whether to position the play widget(s) to the left or right of the slider(s)

  • controls (mpl_interactions.controller.Controls) – An existing controls object if you want to tie multiple plot elements to the same set of controls

  • display_controls (boolean) – Whether the controls should display themselve on creation. Ignored if controls is specified.

Returns

controls

Examples

With numpy arrays:

loc = np.linspace(-5, 5, 500)
scale = np.linspace(1, 10, 100)
def f(loc, scale):
    return np.random.randn(1000)*scale + loc
interactive_hist(f, loc=loc, scale=scale)

with tuples:

def f(loc, scale):
    return np.random.randn(1000)*scale + loc
interactive_hist(f, loc=(-5, 5, 500), scale=(1, 10, 100))
