The High-Low-Average Viewlet is a useful tool to chart and compare the range and average of one or more concurrent “historized” variables in the system. Similar to a stock “High-Low-Close” presentation, the High-Low-Average viewlet shows the extremes of the variable’s values for the selected time frame and desired sample period (rollup). The built-in chart tools enable zooming into specific timeframes within the overall plot range. The chart may be plotted in either Landscape (default) or Portrait modes using the “rotate” flag in the viewlet config dialog.
