Reply #80: Well, the first plot

[Febble]

in that page I linked to (the exit poll swing-shift correlation) simply shows Bush 2000 vote share (in the NEP precincts) correlated against his 2004 vote share. The precincts are coloured red and blue according to whether they had redshift of blue shift, but the main point of the plot is to show the very high correlation between 2000 vote and 2004 vote. OTOH has other plots for similar data sets.

I'll see what else I can find.

Edit: sorry, wasn't clear which link I was talking about:

It's the first plot.
