It will be good to have Freezing Option under Properties for Graphs, Shapes, Linked Pictures/Objects etc. where a user can have an option to lock the objects on screen... and the same should be appearing as constant even if the user scrolls to the left-right & up-down.

This will give End-user a dynamic webpage view/feel especially for huge excel dashboards with specific KPI - graphs and charts appearing on top or on either sides
