Updating fonts and images for powerpoint
When you export a Power View report to Power Point, each view is a separate Silverlight control on its own slide.
You can copy each view and paste it in a different Power Point presentation.
You can delete the Excel file and it will not affect the data on your Power Point slide.
Please visit the most up-to-date Power View documentation on office.
Power View is now a feature of Microsoft Excel 2013, and is part of the Microsoft SQL Server 2012 Reporting Services add-in for Microsoft Share Point Server 20 Enterprise Editions.
You can export an interactive version of your Power View in Share Point report to Power Point 2007, 2010, and 2013.
To change a graph from a chart object to a separate chartsheet, right-click the chart in Excel, choose Location, and select “Place chart as new sheet.” Then reinsert them into your presentation.
If the charts continue to change when updating, save the separate chartsheets as separate Excel workbooks.
