For an overview of box plots, see About box plots.
1. On the Choose Graph page, select Box plot (where rows are detail records).
The Box Plot page appears.
2. From the Subset Variable (for multiple graphs) drop-down list, select a subset variable. The application creates one graph for each value of the selected variable.
3. From the Primary Variable (defines individual boxplots) drop-down list, select a primary variable from a list of numeric variables in the report definition. Each point in the box plot represents a value of the primary variable.
4. From the Secondary Variable (defined boxplot groups) drop-down list, select a secondary variable (optional). Each box represents a value of the secondary variable, as identified by the color key below the graph.
5. Specify the following display options:
Option |
Description |
Notes |
Labels X and Y |
Label the x-axis and y-axis to clarify what is represented by the axes. |
Required. |
Show all points as overlay |
Show all points on the box plot. If cleared, only points outside the upper and lower whiskers are shown.
|
Points in a box plot are jittered, so that if two records have the same value, a point is likely to be displayed for each of them. |
Use gray-scale instead of colors |
Use shades of gray instead of colors in the graph. |
|
Popup |
Display each graph in an individual popup window. If you have popup blocking software installed on your PC, it may prevent these windows from opening. You may want to disable your popup blocking software. For details, see Graph display options. |

6. Click Display.
The application creates the graph using the specified display options. These options apply only to this graph.
For information about copying, printing, or saving a graph as an attachment to a topic, see Working with report graphs.
7. If you point to a region of the graph, the following information appears:
The count may be more than the number of cases because there may be more than one data point for the same case. For example, a case might have multiple adverse events, where each adverse event is a separate data point.
8. If you click a region (Upper Outlier, Upper Whisker, Upper Box, Lower Box, Lower Whisker, or Lower Outlier) of the graph, you can drill down to cases for that region. If you are displaying multiple graphs on the same page, do not click any graph until all the graphs are displayed.
If a case has a value on the boundary between any regions (not including the Upper Outlier or Lower Outlier regions), the case ID is included when you drill down on either of the regions. Cases with values on the boundary of the Upper Whisker or Lower Whisker are not included when you drill down on the Upper Outlier or Lower Outlier regions.
