Adding a Profile Series to a Chart

A profile series chart provides the means to create a virtual data series from actual data series using statistical methods. The result provides a visual comparison to the actual data. To determine the statistical profile, existing chart data can be analyzed:

• Daily: Averages daily data points
• Weekly: Averages weekly data points corresponding with that day
• Monthly: Averages monthly data points corresponding with that day

The profile type establishes the time period over which a statistical process is applied. The statistic types are:

• Maximum: Displays for the highest chart value(s) over the specified time period(s).
• Minimum: Displays for the lowest chart value(s) over the specified time period(s).
• Average: Displays for the mean of chart value(s) over the specified time period(s).

Profile series charts provide a way to compare actual data to statistical data. This is useful in determining whether actual data is above, below, or equal to the statistical comparison. Irregular load patterns become obvious when viewing a profile series chart, and can many times show opportunities for improved energy and process management.
