Pointless charts
I really like the election data compiled at Keele University. I think it's mainlyl because I'm used to dealing with data that is incomplete and sometimes inaccurate. Anyway it's a nice excuse to do some (mainly) pointless charts.This one shows the difference in votes for the three main parties by listing all 600 odd seats (they don't stand in N. Ireland by and large). It is simply shows the party's actual vote in each constituency going from left to right with their highest individual vote to their lowest. The area under the line for each party is their total vote. The Lib-Dems have a few very high votes, and then quite a sharp drop-off. This also shows how the Conservatives didn't actually do too badly in terms of votes.
Of course Tory seats usually have higher turnout than Labour ones (and often larger electorates), so in terms of % Labour's lead was even more. This one shows the same as the first chart, but with the percentage each party scored from highest to lowest.
The above charts were rather contrived. The following ones actually show each party's share of the vote in the same constituency on the same vertical line. First the constituencies ordered in terms of Labour share of the vote, then Tory, then Lib Dem.
