When I generate the report from “Report of Host Performance Graphs” it gives, the report for the last 25 hours and 35 days, is there any way to customize this, like generating a report for the last 7 days or the last 14 days, etc?
Thank you
Hi @sine and welcome to the forum! 
You can go to the mega menu on the left: Customize → Reports and create a custom copy of the report.
