In Windows Task Manager, under the Performance tab, Page File Usage History is shown in a continuous pane, while the CPU Usage History is split up into 8 narrow panes, which make it look like the graph is just "overlaid" with the pane separators.
Why is this? Why not show the graph in a continuous pane?
View => CPU History => One Graph, All CPUs. – Hello71 Jul 20 '10 at 15:16
