I need to graph the data of a sensor in real time

def plot_sensor_data(x, y, graph_name, title, x_label, y_label, color, line_width):
  plt.figure(graph_name)
  plt.plot(x, y, color=color, linewidth=line_width)
  plt.title(title)
  plt.xlabel(x_label)
  plt.ylabel(y_label)
  plt.show()

x = [1, 2, 3, 4]
y = [1, 2, 4, 8]
plot_sensor_data(x, y, 'sensor_data', 'Sensor Data', 'Time (ms)', 'Voltage (V)', 'r', 2)
