586: Vertical Lines on Graph
The vertical lines on graph option allows you to specify whether vertical lines should appear on the graphs at regular intervals. If this option is switched on, vertical lines will appear at every five years on the time series graphs, and at every five points on the scree plots. These lines can be helpful in identifying specific data points. The option toggles the drawing of the vertical lines on and off. A tick is indicated next to the menu item when the vertical lines option is on.
