34 Pivot tables are PSPP's primary form of output. They are analogous to the
35 pivot tables you might be familiar with from spreadsheets and databases.
36 See https://en.wikipedia.org/wiki/Pivot_table for a brief introduction to
37 the overall concept of a pivot table.
39 In PSPP, the most important internal pieces of a pivot table are:
41 - Title. Every pivot table has a title that is displayed above it. It also
42 has an optional caption (displayed below it) and corner text (displayed in
43 the upper left corner).
45 - Dimensions. A dimension consists of zero or more categories. A category
46 has a label, such as "df" or "Asymp. Sig." or 123 or a variable name. The
47 categories are the leaves of a tree whose non-leaf nodes form groups of
48 categories. The tree always has a root group whose label is the name of
51 - Axes. A table has three axes: column, row, and layer. Each dimension is
52 assigned to an axis, and each axis has zero or more dimensions. When an
53 axis has more than one dimension, they are ordered from innermost to
56 - Data. A table's data consists of zero or more cells. Each cell maps from
57 a category for each dimension to a value, which is commonly a number but
58 could also be a variable name or an arbitrary text string.
60 Creating a pivot table usually consists of the following steps:
62 1. Create the table with pivot_table_create(), passing in the title.
64 2. Optionally, set the format to use for "count" values with
65 pivot_table_set_weight_var() or pivot_table_set_weight_format().
67 3. Create each dimension with pivot_dimension_create() and populate it with
68 categories and, possibly, with groups that contain the categories. This
69 call also assigns the dimension to an axis.
71 In simple cases, only a call to pivot_dimension_create() is needed.
72 Other functions such as pivot_category_create_group() can be used for
73 hierarchies of categories.
75 Sometimes it's easier to create categories in tandem with inserting data,
76 for example by adding a category for a variable just before inserting the
77 first cell for that variable. In that case, creating categories and
78 inserting data can be interleaved.
80 4. Insert data. For each cell, supply the category indexes, which are
81 assigned starting from 0 in the order in which the categories were
82 created in step 2, and the value to go in the cell. If the table has a
83 small, fixed number of dimensions, functions like, e.g.
84 pivot_table_put3() for 3 dimensions, can be used. The general function
85 pivot_table_put() works for other cases.
87 5. Output the table for user consumption. Use pivot_table_submit(). */

578 A given pivot_value is one of:
580 1. A number resulting from a calculation (PIVOT_VALUE_NUMERIC). Use
581 pivot_value_new_number() to create such a pivot_value.
583 A numeric pivot_value has an associated display format (usually an F or
584 PCT format). This format can be set directly on the pivot_value, but
585 that is not usually the easiest way. Instead, it is usually true that
586 all of the values in a single category should have the same format
587 (e.g. all "Significance" values might use format F40.3), so PSPP makes
588 it easy to set the default format for a category while creating the
589 category. See pivot_dimension_create() for more details.
591 For numbers that should be displayed as integers,
592 pivot_value_new_integer() can occasionally be a useful special case.
594 2. A numeric or string value obtained from data (PIVOT_VALUE_NUMERIC or
595 PIVOT_VALUE_STRING). If such a value corresponds to a variable, then the
596 variable's name can be attached to the pivot_value. If the value has a
597 value label, then that can also be attached. When a label is present,
598 the user can control whether to show the value or the label or both.
600 Use pivot_value_new_var_value() to create pivot_values of these kinds.
602 3. A variable name (PIVOT_VALUE_VARIABLE). The variable label, if any, can
603 be attached too, and again the user can control whether to show the value
604 or the label or both.
606 4. A text string (PIVOT_VALUE_TEXT). The value stores the string in English
607 and translated into the output language (localized). Use
608 pivot_value_new_text() or pivot_value_new_text_format() for those cases.
609 In some cases, only an English or a localized version is available for
610 one reason or another, although this is regrettable; in those cases, use
611 pivot_value_new_user_text() or pivot_value_new_user_text_nocopy().
