Assume each sample in the data was taken at 30us interval. The current plot shows the sample number in the x-axis. How can I change the x axis of an plt.imshow to the time linspace ?

# time
T = 30e-6
time = np.linspace(0, (data.shape[1]-1)*T, num=data.shape[1])

# plot

plt.ylabel('channel')
plt.xlabel('sec')
plt.colorbar(label="amplitude")
plt.show()
