It took me a while…  If you put your cursor up in the extreme upper left hand corner of that red bar, you get a + sign that allows you to expand the image.  In the expansion you will see text that explains the graphical scales in question.  A pixel (L1 cache), a short bar of pixels (L2 cache), a longer bar (RAM) and finally that huge block of pixels that represent disk latency.
