8. To draw 1-VAR statistical graphs, press [ Graph ] on the STATVAR
menu. There are three types of graph in 1-VAR mode:
N-DIST
(Normal
distribution),
HIST
(Histogram),
SPC
(Statistical Process Control). Select
the desired graph type and press [
]. If you do not set display
ranges, the graph will be produced with optimum ranges. To draw a
scatter graph based on 2-VAR datasets, press [ Graph ] on the
STATVAR menu.
9. To return to the STATVAR menu, press [ 2nd ] [ STATVAR ].
