Visualizing Forecast

Your forecast seemed to be off by over 18% on average. Let's visually compare your forecast with the validation data set to see if we can see why. Your workspace has your forecast object forecast_MET_t and validation data set MET_t_valid loaded for you. Don't forget your validation is 22 weeks long!

Instructions

Convert the mean of your forecast (forecast$mean) into an xts object using the for_dates object for the time index.
Plot your validation data set.
Overlay your forecast on top of the validation.
Don't change the plotting options in either to make it easier to see.
