Statistic	Description

Maximum	The maximum average for the counter for a given polling
	interval over the cumulative elapsed time.

LastValue	The average for the counter over the last polling interval.

Types of graphs

With Device Manager, you can create line, area, bar, and pie graphs. Figure 39 "Line graph" (page 135), Figure 40 "Area graph" (page 136), Figure

41 "Bar graph" (page 136), and Figure 42 "Pie graph" (page 137) provide examples of different types of graphs.
