Reports: Creating a New Pivot Table

A Pivot Table allows you to dynamically summarize large amounts of data for easy analysis and visualization. You can transform data in a table(s) into meaningful summaries easily by using the intuitive drag and drop interface provided by Spiro Reports. With Pivot tables you can easily aggregate and filter the values the way you want it.

Creating a Pivot Table

To create a Pivot View, follow the steps given below:

  • Open the reporting database containing the required data with which you want to create a Pivot Table.
  • Click New Report button in the top left corner to open Create New Report window.
  • In Create New Report window, click Pivot View (Matrix View). The Select Base Table dialog box opens as shown below.

  • Use Select Base Table dialog box to choose the required table in your database on which you want create the Pivot Table and then click OK.
  • This opens a window in Edit Design mode as shown below:

You can also create new Pivot table by opening the corresponding table on which you want to create the pivot table and invoking the New - > New Pivot View option in the toolbar. In Edit Design mode, you will notice that all the columns of the selected table listed as drag and drop items on the left side Column List pane. On the right hand side, you can see the Design Area with shelves to drop the columns and preview area below to view the Pivot created.

Note:

  • If multiple tables in the data base are connected using a Lookup Column then all the columns of the related tables will be listed in the Column List Pane
  • Drag and drop the required columns listed in the Column list pane into the respective shelves in the Pivot tab. You can also select the check box adjacent to each column listed to auto place the columns into the appropriate shelves. After dropping the columns click on the option Click here to Generate Pivot to create the new Pivot Table.

Once you have created the required Pivot Table, click Save button in the toolbar to save the view. In the Save As dialog box that appears, type the Name, Description for the Pivot Table and choose the folder where the view is to be saved and click OK.

Below is a brief description of each of the shelves in the Pivot tab.

  • Column: Distinct data values present in the columns dropped in this shelf will appear as the column headers of your pivot table. You can also have multiple columns dropped in this shelf for summarization. When you add multiple columns, they will be displayed as categorized layers (group within group) of data vertically.
  • Row: Distinct data values present in the columns dropped in this shelf will appear as the row headers of your pivot table. You can also have multiple columns dropped in this shelf for summarization. When you add multiple columns, they will be displayed as categorized layers (group within group) of data horizontally.
  • Data: Values of the columns dropped in this shelf will appear in the body of the pivot table. Values will be summarized based on the summary function that you select. Also it will be categorized to provide the appropriate summary value for each cell corresponding to the row and column value in the table. You can also have multiple columns dropped in the Data shelf for summarization.

The best way to understand how to summarize data in a Pivot table is by example. The following is a table showing sales data of a store.

In the example shown below, pivot table summarizes the data in the above table and presents the total sales in each region grouped by each year. In this example, the pivot table has Date column in Column shelf, Region column in Row shelf, and Sales column in Data shelf. Sales in each region is displayed using a Sum aggregation. Also, Spiro Reports automatically summarizes (in this example it is addition) the values of each row and column based on the summary function that you select. Summary row and column will be added at the bottom and to the right of the pivot table.
Functions that are applied on each of the column in the example here are:

  • Date - Year (all distinct years in the column will be displayed)
  • Region - Actual (all distinct values in the column will be displayed)
  • Sales - Sum (sum of the values in the column will be displayed)

You can also change a data column to use any one of the other functions like: Sum, Count, Average, Standard Deviation etc., depending on the data type of that column, which will be discussed in the next section.

Multiple columns in Row, Column and Data Shelves

Spiro Reports allows you to drop multiple columns (up to 15 columns) in to each of the shelves. When you have more than one column in Column/Row shelf, Spiro Reports automatically groups data in the order they appear from left to right or top to bottom. For example, if you add Product Category and then Product to Rows shelf, all the products will be grouped by their product categories making it easy to see related data and summary information. Similarly, if you add Date and then Region in the Column shelf, then for each distinct year all the regions will be grouped under it to provide the corresponding summary information.

When you add more than one column into Data shelf, columns will be arranged horizontally with each data column (columns in Data shelf) organized as a separate column in the pivot table as shown below.

Summary Rows and Columns

When you create a Pivot Table, Spiro Reports automatically adds summary rows and columns to it, based on the summary function that you select. A row displaying summary values of each group of data will also be added, if you have added more than one column to the Row shelf of your Pivot Table. For each column dropped in the Data shelf there will be a summary column added to the right of the pivot table.

Applying Functions on Columns

Spiro Reports allows you to apply functions like Sum, Count, Average, Min, Max, Year, etc., on the columns to group and summarize data in the Pivot table you create. When you apply a function on a column, a single value will be returned, derived based on the values in the column.
In Spiro Reports, list of Aggregate/Categorical Functions that you can apply on a column varies depending on the data type of the column. The default function for a Numeric (including Currency) data type is Sum and for a Date data type it is Year. If the data type of the column is a string (Categorical/Dimension column) and not numeric, then the default function applied is Actual Values.

To change the this default function that is applied:

  • Open the Pivot table in the Edit Design mode, after dropping the column select the required function (aggregate/category) from the drop-down list present on the column. The drop-down list displays all the applicable functions based on the data type of the column, as shown in the screen-shots below.
  • Once you select the aggregation that you would like to use, you can click the Click here to Generate Pivot link or you can click the View Mode button in the toolbar.

For instance if you want to find the average sales of each product by product category in each region, select Average function from the drop-down list for Sales (Data) column and then click Click here to Generate Pivot link or View Mode button in the toolbar.

The following tables list all the functions along with the description of their functionality that are applicable for the Rows and Columns field.

Numeric and Currency Data Types:

Advanced Summarizing Options

When creating pivots, you can choose how to summarize data i.e., by Sum, Max, Min, Average or by Count in a column, depending on its data type. Apart from these, Spiro Reports also provides advanced summarizing options, which allows you to summarize data values in a column based on other values in the column. For example you can display a running total of sales over each year or you can display the percentage for each region's sale of a product compared to the total sales.




Following are the functions available for advanced summarization:

FUNCTION DESCRIPTION
% of Row Displays data as a percentage of the total for each row.
% of Column Displays data as a percentage of the total for each column
% of Total Displays values as a percentage of the grand total of all the data in the report.
Running Total Displays data in successive cells of the report as a running total. You must select the base field based on which you want to show the items in a running total.
Difference From Displays the data in each cell as the difference from the value in the previous cell, based on the base field provided.
% of Displays the data in each cell as a percentage of the value in the previous cell, based on the base field provided.
% of Difference From Displays the data in each cell as a percentage of differences from the value in the previous cell, based on the base field provided.

Applying Filters

A useful feature of pivot tables is that you can filter columns, to display only required data. Spiro Reports allows you to filter a column for specific ranges, individual values, date ranges, etc. depending on the data type of the column. Spiro Reports offers various filtering options like filter based specific numeric ranges, date ranges, individual values, top 10, bottom 10 etc., Spiro Reports also allows you to apply multiple filters (based on multiple columns) on a pivot . The filtering option discussed in this topic can be applied only when you are designing a Pivot Table (i.e., when you are in design mode) and not in View mode.

To apply a filter, after you have created the required Pivot view:

  • Click Edit Design option in the tool bar.
  • Click Filters tab next to the Pivot tab in the Design Area.
  • Drag and drop the required columns in to the Filters shelf.
  • Once a column is dropped, a list of all the possible options available for filtering the data will be displayed in the box right to Filters shelf as shown in the screen shot below.
  • Filter Options vary depending on the data type of the dropped column.
  • After you have dropped the column, select one or more values to filter by. Selected filter items appears in the third box on the right.
  • Click the button Click Here to Generate Pivot or View Mode button in the toolbar. Data that matches the filter values that you have applied will be displayed. However, if you want to exclude specific data from the view, select Exclude Items option in the drop down list at the top of the filter items box.

The Filtering options are the same for all types of reports that you create in Spiro Reports namely charts, pivot table & summary views. The filtering options provided varies based on the data type of the column dropped. Refer Filters section under Charts topic to know about various Filter Options.

Providing User Filters

Spiro Reports also allows you to include dynamic filters in the Pivots view mode called User Filters. This enables your users who access the report, to apply filters on the report data displayed using the filter columns exposed as part of the User Filters. The filter columns included in User Filters can be displayed using a variety of display components like Drop Down boxes, Slider, Date range chooser etc., to suit your needs.

The steps to provide User Filters are same for all types of reports that you create in Spiro Reports. Refer User Filters section under Charts topic for details on how to provide User Filters for various column types (Data types).
