Graphs of Input Data and Graphs of Block Data.
Unlike Graphs of Input Data, Graphs of Block Data use the currently selected (continuous) block of data in the active spreadsheet to specify input data for the graph.
Note that these graphs are entirely independent from the concept of "input data." They process values (numbers) from whatever is currently selected in the block and ignore the "meaning" of those numbers (e.g., the numbers can be raw data or values of correlation coefficients). These graphs offer an effective means of visualizing, exploring, and efficiently summarizing numeric output from analyses displayed in results spreadsheets (e.g., histograms of Monte Carlo output scores in the SEPATH module, or a box plot of aggregated means from a multivariate multiple classification table in the ANOVA module).
Although the most convenient (and you could say most logical) way to
select Graphs of Block Data is
via the shortcut menu associated with the respective block selected in
a spreadsheet, Graphs of Block Data are also available from the Graphs menu or the STATISTICA
Start button menu. When creating Graphs
of Block Data, you can select from default graphs (e.g., Histogram: Block Columns or Line Plot: Block Rows), or you can create
your own custom graphs for either the selected cells in the rows or columns
or of all cells in the selected rows or columns (i.e., going beyond the
values that are selected in the block).

Custom graphs. Select one of the four custom graph options to display the Select Graph dialog which provides a variety of options for creating customized graphs.
For specific information on a custom graph, click on the graph name below.
Customizing Graphs.
For example, if you want to include a normal fit on the histograms created using Histogram: Block Columns, select Histogram: Block Columns in the Customize Graph Menu dialog, click the Edit button, and switch the Graph SubType to Normal Fit. All subsequently created Histogram: Block Columns plots will include a normal fit to the data.
