Crosstabs have different data, layout, and format options than tables or charts.
Ad Hoc Editor’s Standard Crosstab View |
|
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. |
Crosstab Measures
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 Calculation |
| • | Change Time Balance Calculation |
| • | Move Up or Move Down or Move Left or Move Right |
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.
Pivoting
You can pivot a crosstab in two ways:
| • | Pivot the entire crosstab by clicking |
| • | 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. |
Slicing
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.
Summarizing
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) |
| • | To select the summary function and data format for a measure, right-click the measure label and select from the context menu. Note that you can’t change the summary function on custom fields that calculate percents (Percent of Total, Percent of Column Group Parent, and Percent of Row Group Parent). |
| • | The summary functions for numeric fields are Sum, Average, Maximum, Minimum, Distinct Count, and Count All. Distinct Count is the number of different items in the row or column; Count All is the total number of items. For instance, if there are 3 widgets of type A and 3 widgets of type B, Distinct Count is 2 and Count All is 6. |
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.
Sorting
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: |
| 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.
Changing How Totals Are Calculated Using Time Balance
By default, crosstabs show the Totals of numeric values as the sum of the values in a column. For example, if the crosstab view displays product sales grouped by month, the crosstab displays the total sum sold during those months as the Totals value.
You can change the data that the crosstab displays as the Totals value for a period of time using the Time Balance options. These options allow you to change the Totals to display the first and last numeric values for the period. For example, if you want to see the number of products left in your inventory at the end of a certain time period, use the Time Balance Last option and the Totals fields will display the last numeric value entered for the time period. If you want to see the number of products in your inventory at the beginning of the time period, use the Time Balance First option.
| Changing the time balance calculation requires the crosstab to use the Date field. You cannot drill through the data when using a Time Balance option other than the default or when using Day of Week for the grouping. |
To change the totals calculation using time balance:
| 1. | In the Ad Hoc view, right-click the column or row header. |
| 2. | Select Change Time Balance from the context menu. |
| 3. | Select the option you want to use. You can select one of the following: |
| • | Time Balance Default. This option displays the sum of all the numeric data for a period of time as the Total value. |
| • | Time Balance First. This option displays the first numeric value for a period of time as the Total value. For example, if the period of time is a month, the crosstab will display the first numeric value entered for the month. |
| • | Time Balance Last. The option displays the last numeric value for a period of time as the Total value. For example, if the period of time is a month, the crosstab will display the last numeric value entered for the month. |
The crosstab is updated to show the new Total values.
Changing the Data Format
You can change the formatting for rows and columns containing numeric data, such as dates and monetary amounts. By default, non-integer fields use the -1,234.56 data format; integers use -1234.
To change the data format for a column:
| 1. | In the Ad Hoc view, right-click the column or row header. |
| 2. | Select Change Data Format from the context menu. |
| 3. | Select the format you want to use. These options vary, depending on the type of numeric data contained in the column. |
The data in the column or row now appears in the new format.
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.
