Create Pivot Tables & Pivot Charts in an Excel Worksheet

This technical tip show how developers can create Pivot Tables and Pivot Charts using Aspose.Cells component. A Pivot Table is an interactive summary of records. For example, you may have hundreds of invoice entries in a list on your worksheet. A Pivot Table can total the invoices by customer, product or date. In MS Excel, y ou can quickly re - arrange the information in the Pivot Table by dragging the buttons to a new position. A Pivot Chart is an interactive graphical representation of the data in a Pivot Table. This feature was firstly introduced in Excel 2000. Using a Pivot Chart makes it even easier to understand your data since the Pivot Table creates your subtotals and totals for you automatically. Aspose.Cells is a feature rich component that supports to create Pivot Tables and Pivot Charts for your requirement. Aspose.Cells provides some special set of classes that are used to create and set the PivotTables. These classes are used to create and set PivotTable objects, which act as the basic building blocks of a PivotTable .
