Not plotting 'y' when using m.plot(forecast)

[Lockee45]

Hi,

I am following the 'full simple model' step by step with no issue, but when plottting forecast using m.plot(forecast), I can only access yhat data for the period in the futur, without plotting 'y' and past data:

Do you know where the problem is coming from? I am using Jupyter NTB and strictly following the step by step.

Thank you
