Because banana prices are uniformly smaller than prices for apples and bread, the layer for Bananas is at first entirely hidden behind the other two layers. The apples price is hidden behind the bread price for some months. Use the Line element to see prices for all three clearly.
The layers for the plot are ordered by the order of entry of variables, as shown in the legend. The graph shows that banana prices are uniformly smaller than both apple and bread prices. On average, apple prices dominate bread prices up to the year 2000. After this, bread prices are generally higher than apple prices. Also note that the price of bread increases at a smoother rate than prices for apples and bananas. The line plots for Apples and Bananas are very jagged, with a lot of spikes and dips from year to year.
