About PivotTable reports

A PivotTable report is an interactive table that you can use to quickly summarize large amounts of data. You can rotate its rows and columns to see different summaries of the source data, filter the data by displaying different pages, or display the details for areas of interest.

How PivotTable reports organize data:

  • Fields and items
    A PivotTable report contains fields, each of which corresponds to a column (or OLAP dimension) in the source data and summarizes multiple rows of information from the source data. Fields in a PivotTable report list items of data across rows or down columns. The cells where the rows and columns intersect show summarized data for the items at the top of the column and the left side of the row. For example “Gender”, “Age” and “Mstatus” can be a columns dimensions, and “Mprice” can be a row dimension.
  • Data fields and cells
    A data field, provides the values that are summarized in the PivotTable report. For example the “Vote Count” as Data field.
  • Summary functions
    To summarize the data field values, PivotTable reports use summary functions, such as Sum, Count, or Average. These functions also provide subtotals and grand totals automatically, where you choose to show them.
  • Viewing details
    In most PivotTable reports, you can view the detail rows from the source data that make up the summary value in a particular data cell.
  • Changing the layout
    By dragging a field button to another part of the PivotTable report, you can view your data in various ways and calculate different summarized values.
  • Graphical views of PivotTable data
    A PivotChart report is an interactive chart that you can use to view and rearrange data graphically, in a similar manner to a PivotTable report. A PivotChart report always has an associated PivotTable report in the same workbook, and includes all of the source data from the associated report. And like a PivotTable report, a PivotChart report has field buttons that you can use to display different data and change the layout.

Elements of a PivotTable report

  • Row fields
    Fields from the underlying source data that are assigned a row orientation in a PivotTable report. A PivotTable report that has more than one row field has one inner row field, the one closest to the data area. Any other row fields are referred to as outer row fields. For example, “Gender”, “Age” and “Mstatus”.
  • Column field
    A field that's assigned a column orientation in a PivotTable report. A PivotTable report can have multiple column fields just as it can have multiple row fields. Most indented format PivotTable reports do not have column fields. For example “Mprice”
  • Page field
    A field that's assigned to a page, or filter, orientation. When you click a different item in a page field, the entire PivotTable report changes to display only the summarized data associated with that item.
  • Page field item
    Each unique entry or value from the field, or column, in the source list or table becomes an item in the page field list.
  • Data field
    A field from a source list or database that contains data to be summarized. For example “Vote count”
  • Data area
    The part of a PivotTable report that contains summary data. The cells of the data area show summarized data for the items in the row and column fields. Each value in the data area represents a summary of data from the source records, or rows

 

 

About adding and removing fields

Depending on how the person who created a PivotTable list has set up the data, you might be able to display additional data or remove data that you don't want to view or summarize.

  • Viewing the fields available to the PivotTable list
    Use the field list to view the list of fieldsets and fields that are available from the source data, and to add fields to the row, column, filter, data, and detail areas of the PivotTable list. In the field list, the fields that are not bold are available but not yet displayed in the PivotTable list. The bold fields are already displayed. You can scroll and click the expand indicators next to the fieldsets to show or hide fields in the field list.
  • Adding fields to the detail area
    Use detail fields to display all of the available detail data and see what data is available to be summarized. When you add fields to the detail area, you display all of the detail records from the source data for the fields. Field names become column labels, and the detail records are displayed in rows below the column labels.
  • Adding fields to the row or column area
    Use row and column fields to summarize and compare data. These fields display the unique items of data within a field down rows or across columns. The cell at each row and column intersection summarizes the data for an item.
  • Adding fields to the data area
    Data fields provide the values to be summarized in the PivotTable list. When you add a field to the data area, the values from the field are summarized for the row and column field items.
  • Adding fields to the filter area
    A filter field is similar to a page field in a Microsoft Excel PivotTable report. Use filter fields to confine the view to a particular part of the available data. When you select an item in a filter field, data is displayed and calculated only for that item. For example, if you add a Region filter field, you can have the PivotTable list display and calculate data for the regions you select.
  • Removing fields
    To eliminate data that you don't want to see or summarize, you can remove fields from the PivotTable list layout. Removing a field does not remove it from the available source data. A field that you remove is no longer displayed in the PivotTable list, but it remains available in the field list for viewing
  • Moving fields
    After you add a field to a PivotTable list, you can move it to other areas. When you move a field, you change the layout of the PivotTable list, and you change the data that's displayed and the summaries that are calculated.
  • Viewing information about fields
    You can view information about fields in a PivotTable list, including information about the field in the source database from which the data is taken and the type of data that the source database supplies for the field.
