The Report button is used to print the Grid and/or Chart displayed.
Specify what you would like to print using the Options menu, then choose Print.
The Document Options dialog box has three tabs: Page, Header/Footer, and Report Options.
Please note: You could use the right-click menu (see Getting Started with C1OLAP) to print the C1Olap web part also, but only the information displayed will be printed. See Printing a Web Part for more information.
If you would like to copy your data to an Excel spreadsheet, select the data from your Grid by clicking the upper left cell, and then pressing Ctrl+C. All of the data will be highlighted in light blue. Paste (Ctrl+P) into Excel. The row and column headers will be included with your data.
