Data analysis
In any display, you can view the statistics of data runs, including minimum
value, maximum value, mean value, standard deviation, and count (or number
of points). In a graph, the area statistic is also available.
A graph also allows you to apply curve fits; draw predictions; and find
coordinates, distances, and slopes on data plots.
