Can we embed an excel worksheet into the RQM dashboard?

Hi Seema,
You will need to put your image of the chart on a server that can be reached by a URL that is accessible from the RQM server machine (It will not go through  any firewalls you might have in place!).

The steps are:
On the dashboard use the "External Content" widget.
In the settings of that widget you can specify the external URL for your image graph:
For example:
http://www.ibm.com/images/portal/X793998X98785J28/08152011_Redbooks.png

In case this is blocked by your infrastructure you can also try to use the Tomcat server of your CLM installation
Create the folder C:\Program Files\IBM\JazzTeamServer\server\tomcat\webapps\ROOT\static
(or where you have installed your server) and put your images in there.
For example C:\Program Files\IBM\JazzTeamServer\server\tomcat\webapps\ROOT\static\mychart.jpg
The URL to use  inside the widget is then something like https://clm-server:9443/static/mychart.jpg

Hope this helps,
