Reading the Microsoft TechNet article "Test results: Extra-large scenario (FAST Search Server 2010 for SharePoint)", I came across this graph.
Now, am I stupid (and if so, could someone please enlighten me), or is this graph just stupid? To me, it seems like it's created with MS Paint instead of reflecting real values - I can not make sense of the graph as it seems like any given value on the horizontal axis (Queries per second) can result in multiple values on the vertical axis (Latency).
EDIT: Thanks to all who contributed, the curves (not graphs) make more sense to me now. My conclusion to the original question is somewhere in the middle. I admit some stupidity on my own behalf, but still think the graphical representation of the data is quite stupid, as it fails to clearly communicate what it should.
