The Normal Q-Q Plot plots the distribution of a single data set against the normal distribution. To change a Q-Q plot to a Normal Q-Q plot, change either the X column or Y column property on the Property Manager Plot page to None.
The y=x line is also plotted on both the Q-Q plot and the normal Q-Q plot.
Q-Q plots show data as symbols with a y=x line
This plot compares two data sets that are closely related,
so the data fall almost always along the y=x line.
