The Area Chart Viewlet enables the user to display graphically quantitative data from one or more similar variables. Similar to line charts, the area charts often enable to user to visualize the underlying data more clearly. The chart may be plotted in either Landscape (default) or Portrait modes using the “rotate” flag in the viewlet config dialog.
