There appears to be an unexpected behavior in the way multiple graphs are laid out initially. Several graphs appear in the same horizontal section going beyond the boundary of the browser. You have to scroll a lot to get to view them all.
However, if one clicks on any other report on the same page the graph will refresh with a more attractive layout, one that fits horizontally as many graphs as its possible based on the graph size and the current zoom level of the browser. (in the attached example a single graph per row can fit in the browser window)
