Classic menus. The Graphs - Graphs of Input Data - Box-Whisker by submenu contains commands to plot four bivariate different (3-dimensional) histograms.

Choose one of the four types of graphs to represent the distribution of categorized values of the currently highlighted variable. The box plots resulting from this option represent the currently highlighted variable's central tendency and variability for each category of the grouping variable. As measures of central tendency, you can choose between plotting the means and medians of the values in each category and for each, their respective measures of variability; standard deviations or standard errors, and ranges (other options are available via STATISTICA's Graphs menu graphs; see also, Categorized Box and Whisker Plots).

In some results spreadsheets, the selection of the grouping variable is pre-determined by some global grouping variable (i.e., the grouping variable designated in an analysis dialog). When this is the case, Statistica will incorporate the (pre-determined) grouping variable name in the appropriate Graphs of Input Data option (e.g., Box-Whisker by Gender). In most other cases, Statistica will prompt you to select the grouping variable via the Select Variable dialog.

When you are prompted to select a grouping variable that will be used to categorize the values of the currently highlighted variable, the Select Variable dialog box will be displayed. Once you have selected the grouping variable from this dialog box, another dialog box will be displayed (Codes) prompting you to enter the values (codes) for the previously-specified grouping variable (if you leave the list of codes empty, all distinctive values of the grouping variable will automatically be used). After the codes have been entered, a plot displaying separate box and whisker plots for each category of the grouping variable will be produced.

Many other types of box and whisker plots and other range and variability graphs are available via Statistica's Graphs menu graphs.  In order to produce box plots representing the distribution of the values in cases (and not variables), use either the Graphs of Block Data - Custom Graph for Entire Row or Graphs of Block Data - Custom Graph from Block by Row options from the spreadsheet shortcut menu (instead of transposing your data file).
