Distribution of a value in 2D qubit lattice as a color map.

Main aliases

cirq.Heatmap, cirq.vis.heatmap.Heatmap

Heatmaps

Args
`value_map`	dictionary A dictionary of qubits or QubitTuples as keys and corresponding magnitude as float values. It corresponds to the data which should be plotted as a heatmap.
`title`	str, default = None
`plot_colorbar`	bool, default = True
`annotation_map`	dictionary, A dictionary of QubitTuples as keys and corresponding annotation str as values. It corresponds to the text that should be added on top of each heatmap polygon unit.
`annotation_format`	str, default = '.2g' Formatting string using which annotation_map will be implicitly contstructed by applying format(value, annotation_format) for each key in value_map. This is ignored if annotation_map is explicitly specified.
`annotation_text_kwargs`	Matplotlib Text **kwargs,
`colorbar_position`	{'right', 'left', 'top', 'bottom'}, default = 'right'
`colorbar_size`	str, default = '5%'
`colorbar_pad`	str, default = '2%'
`colorbar_options`	Matplotlib colorbar **kwargs, default = None,
`collection_options`	Matplotlib PolyCollection **kwargs, default {"cmap" : "viridis"} vmin, vmax: colormap scaling floats, default = None

Methods

plot(
    ax: Optional[plt.Axes] = None,
    **kwargs
) -> Tuple[plt.Axes, mpl_collections.Collection]

Plots the heatmap on the given Axes.

Args
`ax`	the Axes to plot on. If not given, a new figure is created, plotted on, and shown.
`kwargs`	The optional keyword arguments are used to temporarily override the values present in the heatmap config. See init for more details on the allowed arguments.

Returns
A 2-tuple `(ax, collection)`. `ax` is the `plt.Axes` that is plotted on. `collection` is the collection of paths drawn and filled.
