Just uploaded a PowerPivot Workbook to a PowerPivot Gallery on Sharepoint 2013 site. I opened it but only the slicers are shown, not the Pivot chart.
At the position of the pivot chart, there is only an [x] icon.
Apart from that, I don't see any notice, error information or similar.
I'm the admin of both SharePoint farm and SQL Server.
I googled but did not find anything, not sure what I missed.
Edit 1: Menu bar also deos not work, nothing happens on click. I think there is something wrong with my Excel application on SharePoint.
