I am trying to run a measurement, measuring a temperature over time, using QCoDeS measurement drivers. I would like to view a live plotting of the data. Preferably using Matplotlib.Animation package. How best to do this?

I have tried the below but the graph does not update.

Etime = ElapsedTimeParameter('Etime')

meas = Measurement()
meas.register_parameter(Etime)
meas.register_parameter(T1, setpoints=[Etime])

fig, ax = plt.subplots()
xdata, ydata = [], []
ln, = ax.plot([], [], 'ro')

def init():
    ax.set_xlabel('Time (s)')
    ax.set_ylabel('Temperature (K)')
    return ln,

def update(now, temp):
    xdata.append(now)
    ydata.append(temp)
    ln.set_data(xdata, ydata)
    return ln,

ani = FuncAnimation(fig, update, len(ydata), init_func=init, blit=True)

with meas.run() as datasaver:
    Etime.reset_clock()
    for _ in range(20):
        temp = T1()
        now = Etime()
        update(now, temp) 
        datasaver.add_result((T1, temp), (Etime, now))
        plt.show()
        time.sleep(1)
    
dataset = datasaver.dataset
