# Plotting one-step-ahead predictions

Now that you have your predictions on the Amazon stock, you should plot these predictions to see how you've done.

You made predictions over the latest 30 days of data available, always forecasting just one day ahead. By evaluating these predictions you can judge how the model performs in making predictions for just the next day, where you don't know the answer.

The `lower_limits`

, `upper_limits`

and `amazon`

DataFrames as well as your mean prediction `mean_forecast`

that you created in the last exercise are available in your environment.
