The History Line Chart viewlet is used to plot values for multiple similar variables over time. For each interval over the selected time period, the viewlet can plot the maximum, minimum, average, or sum of the variable. One of the most informative history viewlets, the peaks and valleys seen in a History Line Chart can give the user an instant view of energy consumption and efficiency over time. The user also has the ability to manually drag a marquee over a section of the line or lines to zoom in and view any particular range, and then use the horizontal pan bar along the top of the viewlet to scroll across the line.
