draw_layer_error_map

draw_layer_error_map(layer_error, embedding, colorscale='Bluered', color_no_data='lightgray', color_out_of_scale='lightgreen', num_edge_segments=16, edge_width=4, height=500, highest_rate=None, background_color='white', radius=0.25, width=800)

Draw a map view of a LayerError.

Parameters

• layer_error (LayerError) – The LayerError to draw.
• embedding (Union[Embedding, BackendV2]) – An Embedding object containing the coordinates and coupling map to draw the layer error on, or a backend to generate an Embedding for.
• colorscale (str) – The colorscale used to show the rates of layer_error.
• color_no_data (str) – The color used for qubits and edges for which no data is available.
• color_out_of_scale (str) – The color used for rates with value greater than highest_rate.
• num_edge_segments (int) – The number of equal-sized segments that edges are made of.
• edge_width (float) – The line width of the edges in pixels.
• height (int) – The height of the returned figure.
• highest_rate (Optional[float]) – The highest rate, used to normalize all other rates before choosing their colors. If None, it defaults to the highest value found in the layer_error.
• background_color (str) – The background color.
• radius (float) – The radius of the pie charts representing the qubits.
• width (int) – The width of the returned figure.

Raises

• ValueError – If the given coordinates are incompatible with the specified backend.
• ValueError – If backend has no coupling map.
