Use this operator to create a graphical representation of a data set's attributes using the box-and-whisker diagrams.
For each box-and-whisker, the following applies.
- The bottom and top of the box indicate the 25th and 75th percentile of the data.
- The band in the middle of the box indicates the 50th percentile (median).
- The bottom and top of the whisker represents the minimum and maximum within the data set.
- The mean is denoted by a small circle.
The Box Plot operator allows you to choose the following three attributes (columns) in the data table:
- X dimension (Analysis Type) - Accepts a category-type attribute to construct the box plot's X-axis.
- Y dimension (Analysis Value) - Accepts a numerical attribute to construct the box plot's Y-axis.
- Grouped dimension (Analysis Series) - Accepts a category-type attribute, which is shown in diagrams of different colors.
Input
