you want to show an Excel chart in SharePoint, there is
an Excel Web Access web part that is especially created
for such integration. Unfortunately Microsoft has not yet
provided a Power BI web part, which would be the best solution
when you want to show a Power BI report in SharePoint.
There are however other ways to integrate a Power BI report
into SharePoint, and in the demo below Peter Kalmström shows
one method for public data and one for restricted data.
BI has a 'Publish to web' feature. It gives an embed
code that you can copy and paste into a page in edit
mode with the Embed Code button.
This method works well when you want to show public
data, but it is not secure. It gives a link that does
not require login, so anyone who has the embed link
can look at the report in Power BI.
For data that should be kept secure, I recommend
to insert a screenshot of the report in SharePoint and
link it to Power BI. If you copy the URL from the address
field in the report, users will be asked to log in when
they click on the linked screenshot.
