Plot individual components
It is also possible to extract other inferred quantities from your time-series decomposition object. The following code shows you how to extract the observed, trend and noise (or residual, resid) components.
observed = decomposition.observed
trend = decomposition.trend
residuals = decomposition.resid
You can then use the extracted components and plot them individually.
The decomposition object you created in the last exercise is available in your workspace.
