Oh, I see what you're talking about Brad. Temperature anomaly graphs which take account of the diurnal range are even rarer than the ones with the uncertainty range estimates included. There are some graphs of global maximum temperature and minimum temperature from 1950 to the early 1990s in this 1997 paper which is available free to view on this link:
If you look at Fig 1 of the paper you'll see why climate scientists prefer not to plot this sort of graph - the temperature rise per decade for the maximum temperature is half the rate of the rise of minimum temperature, suggesting that two thirds of global warming is occurring at night. If they plot mean temperature this detail is hidden.
I might as well include this link as well, criticism of the above paper by AGW sceptic Warwick Hughes:
