qiskit.visualization.plot_gate_map

plot_gate_map(backend, figsize=None, plot_directed=False, label_qubits=True, qubit_size=None, line_width=4, font_size=None, qubit_color=None, qubit_labels=None, line_color=None, font_color='w', ax=None, filename=None)

Plots the gate map of a device.

Parameters

• backend (BaseBackend) – The backend instance that will be used to plot the device gate map.
• figsize (tuple) – Output figure size (wxh) in inches.
• plot_directed (bool) – Plot directed coupling map.
• label_qubits (bool) – Label the qubits.
• qubit_size (float) – Size of qubit marker.
• line_width (float) – Width of lines.
• font_size (int) – Font size of qubit labels.
• qubit_color (list) – A list of colors for the qubits
• qubit_labels (list) – A list of qubit labels
• line_color (list) – A list of colors for each line from coupling_map.
• font_color (str) – The font color for the qubit labels.
• ax (Axes) – A Matplotlib axes instance.
• filename (str) – file path to save image to.

Returns

A Matplotlib figure instance.

Return type

Figure

Raises

• QiskitError – if tried to pass a simulator, or if the backend is None, but one of num_qubits, mpl_data, or cmap is None.
• MissingOptionalLibraryError – if matplotlib not installed.

Example

from qiskit import QuantumCircuit, execute, IBMQ
from qiskit.visualization import plot_gate_map
%matplotlib inline
 
provider = IBMQ.load_account()
accountProvider = IBMQ.get_provider(hub='ibm-q')
backend = accountProvider.get_backend('ibmq_vigo')
plot_gate_map(backend)
