My all-time favorite example of this problem is the cardiac cycle
figure that includes 1) the heart sounds at the top, 2) below them is
the ECG, 3) then a graph showing 3 pressures curves [aortic,
ventricular and atrial], 4) below that is a ventricular volume curve, 


Connecting this to the eponym discussion,  there's a short and handy term for this: Wiggers' diagram.  A particularly nice term for us, I should think, as it honors someone noted for teaching among other things.

The main problem I encounter with that figure is the way the students interpret the valve condition bars.  Some people have inordinate difficulties distinguishing between the action of opening and the condition of being open.  After studying that diagram, some will treat the the question of exactly when the aortic semilunar valve opens as being meaningless... "this whole time of course." 

In addition to the historical reference, I like eponyms for a reason not yet raised - with a few notable exceptions like Langerhans, they make nice unique computer search terms.
