The Column Chart Viewlet
The Column Chart Viewlet can be used to plot the relative value for multiple variables over time. For each interval over the selected time period, the user can plot the maximum, minimum, average, or sum of the variable. New viewlet functionality allows the user to manually drag a marquee over a selection of columns to zoom in and view any particular section of the graph, and then use the horizontal pan bar along the top of the viewlet to scroll through the columns.
