No series value and projections on chart

I am stuck trying to solve the W1_Alignment. I should get:

EXPECTED - Chart with X-Axis from 1100-1250 and Y Axes with series value and projections. Projections should be time stepped 1 unit ‘after’ series

but i see just one time series. The code is the following:

plt.figure(figsize=(10, 6))
zoomed_time_valid = time[1100:1250]
zoomed_x_valid = series[1100:1250]

naive_forecast = series[1100:1250]
plot_series(zoomed_time_valid, zoomed_x_valid,start=0,end=150)
plot_series(zoomed_time_valid,naive_forecast,start=1,end=151)

I am sorry but I am not sure if I get your issue correctly . Could you please explain it again?
Thankyou
