This section describes the Boxes tab that is associated with a box plot. To access the box plot properties, right-click near the center of a plot, and select from the pop-up menu.
The Boxes tab controls attributes of the box plot. The Boxes tab is shown in Figure 5.18.
The Boxes tab contains the following UI controls:
sets the length of the whiskers.
A length of w means that whiskers are drawn from the quartiles to the farthest observation not more than w times the interquartile distance (Q3–Q1).
specifies whether each whisker is capped with a horizontal line segment.
specifies whether each box is drawn with notches. The medians of two box plots are significantly different at approximately
the 0.05 level if the corresponding notches do not overlap.
specifies whether each box is drawn with mean markers that extend one standard deviation from the mean. The central line of
the mean marker indicates the mean. The upper and lower extents of the mean marker indicate the mean plus or minus one standard
deviation.
specifies whether each box is drawn with mean markers that extend two standard deviation from the mean.
specifies whether the mean markers are drawn as a diamond or an ellipse.
sets the fill color for each box.
sets the outline color for each box.
sets the color for mean markers.
specifies whether each box is filled with a color. When not selected, only the outline of the box is shown.
