Set Zoom Level to Page Width in Report URL to display in Dashboard

Hi,

I tried to set the 'Zoom level to Page Width' to the report URL in the Iframe that should be displayed in the dashboard in crm 2013.

Just like below URL,

servername/.../Report.aspx;rs:Command=Render&rc:Zoom=Page+Width

But this is not working, it is defaulting to Zoom option = 100%.

I want to set (Zoom = Page Width) to the report to display in the dashboard.

Can someone please help me on this.

Thanks,
