The Column Chart viewlet can be used to plot the aggregate or relative value for multiple variables over time. For each rollup interval over the selected time period, the Column Chart can plot the maximum, minimum, average, or sum of the variable. The Column Chart Viewlet is a useful tool for presenting historical data in a variety of ways, for instance, comparing locations against each other or aggregating sub-meters in a building. Viewlet functionality allows the user to manually drag a marquee over a selection of columns to zoom in to 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. Selecting “show all” will revert back to displaying the entire time range indicated in the configuration menu.
