This section describes crosstabs based on Topics and Domains. For information about crosstabs based on OLAP connections, refer to Working with OLAP Connection-based Crosstabs and Working with Topics.
Crosstabs have different data, layout, and format options than tables or charts.
If you selected Crosstab when you created a view, as described in Ad Hoc View Types, the following sections explain tasks specific to your crosstab development.
Using Fields in Crosstabs
Fields can be added to crosstabs as row groups or column groups. Measures can be added to crosstab rows or columns as well, but all measures must be included as either a row or a column – that is, you can add one or more measures as columns, or add one or more measures as rows, but you cannot have one measure as a column and another as a row in the same crosstab.
Crosstab Rows and Columns
When creating a crosstab view, keep in mind that row and column groups are arranged in hierarchies. Drag the group headings to rearrange the hierarchy; you can also right-click a heading and select a Move option from the context menu or press the cursor keys. Rearranging the groups may change the preview data in the editor.
To add a field or measure to a crosstab group:
|1.||In the Data Source Selection panel, click to select the field(s) you want to add to the crosstab as a group. Use Ctrl-click to select multiple items.|
|2.||Drag your selection into the Columns or Rows box in the Layout Band.|
Measure labels are displayed in the crosstab based on their status as a row or column:
|•||Measures included as rows appear in the crosstab below the Measures heading.|
|•||Measures included as columns appear in the crosstab to the right of the Measures heading.|
You can right-click a measure in the crosstab to open a context menu that provides these options:
|•||Change Summary Function|
|•||Change Data Format|
|•||Remove From Crosstab|
|•||Move Up or Move Down|
Measures are arranged in cells. You can add any number of measures. All the measures appear together in every cell. To rearrange the measures, drag them in the measure label area.
You can pivot a crosstab in two ways:
|•||Pivot the entire crosstab by clicking . The row and column groups switch places. For more information, see Creating a View from a Domain.|
|•||Pivot a single group:|
|•||To pivot a single row group, right-click it and select Switch To Column Group.|
|•||To pivot a single column group, right-click it and select Switch To Row Group.|
Pivoting removes any custom sorting applied to headings in your crosstab. It does not affect column or row sorts.
The slice feature lets you keep or exclude group members in a crosstab. To slice, right-click a group member and select:
|•||Keep Only to remove all groups except the selected one from the crosstab.|
|•||Exclude to remove this group from the crosstab.|
Use Ctrl-click and Shift-click to select multiple groups to keep or exclude.
You can select multiple row groups or multiple column groups; you can't slice by both row groups and column groups at once. Compare slice to drill-through, drill to details, and filtering.
For more information about filtering, see Using Filters and Input Controls.
All row and column groups are summarized automatically:
|•||To turn off a group summary, right-click any heading in the group and select Delete Row Summary or Delete Column Summary from the context menu. To reapply the summary, right-click the heading and select Add Row Summary or Add Column Summary.|
The Delete Summary option is available only for the outermost group on either axis (that is, either the outermost row group or the outermost column group)
Collapsing and Expanding Members
By default, the editor displays each row and column group of a crosstab in a collapsed state. This means you can see the totals for the group, but not the measures for its individual members. To see measures for a group’s members, right-click the group label and select Expand Members.
When a group’s members are expanded, select Collapse Members from the same menu to hide the measures. Collapsing an outer group also collapses its inner groups. The Expand Members and Collapse Members options are available only for outermost groups, or for inner groups nested in an expanded outer group.
When you collapse a group, its summary is automatically displayed; this prevents invalid crosstab layouts in which there is nothing to display for some totals if the summary has been deleted previously.
Merging and Unmerging Crosstab Cells
By default, the editor merges cells containing the same data into a larger, single cell to make the crosstab data easier to read. The following image shows a crosstab with merged cells.
To display all of the individual cells in the crosstab instead of merged cells, hover over and select Unmerge crosstab cells. The following image shows a crosstab with unmerged cells.
To merge the crosstab cells, hover over and select Merge crosstab cells.
By default, the rows and columns of crosstabs are sorted in alphabetical order of the group names.
To sort your crosstab:
|•||Right-click the heading you want to use for sorting and select one of these options:|
The crosstab is updated to reflect your sorting option. A blue dot appears in the context menu next to the currently applied sort option.
When the crosstab includes more than one row group or more than one column group, the inner groups are also sorted according to your selection. Only one measure can be used for sorting at any one time; changing the sort order for another measure resets all others to the default.
To filter top or bottom N values:
You can filter the numeric data shown in a crosstab to show only the rows with the top or bottom N values, where N is a number that you specify. For example, you can filter a crosstab to display only the top 10 values in a column.
|1.||Right-click the heading you want to use for filtering and select one of these options:|
|•||Filter Top N Values|
|•||Filter Bottom N Values|
|•||Don't Filter Values|
|2.||Enter the number of values you want to show in the crosstab.|
|3.||Select whether to show an aggregate of the unranked values in the crosstab.|
|4.||Select whether to apply the filter across all row groups.|
The crosstab is updated to reflect your filter option. The icon appears in the heading when filtering a column for the top N values, while the icon appears when filtering for the bottom N values. A blue dot appears in the context menu next to the currently applied filter option. Only one measure can be used for filtering at any one time; changing the filtering or sort order for another measure resets the filtered column.
Resizing and Layout
Many of the layout and formatting options that are set manually in tables are set automatically in crosstabs. In particular, row and column sizes are fixed and no spacer is available.
Drilling Through Data
Drill-through functionality is available for crosstab data. A drill-through table displays the supporting details for the selected roll-up value.
To view the drill-through table for a value in your crosstab:
|•||Click hyperlinked data to display additional columns from that specific fact data.|
By default, the drill-through table opens in its own window or tab, depending on your browser settings.
