Updated this with 1922 to 2007 figures. Made this to see if politics was diversifying or FF stranglehold on the country continues.
Oh heres the complete data I need, Dail Eireann election summary.
As always constantly trying to see which service does it better. That stack chart isn't very good, it doesn't display the years right,ie the length of the governments...,which mirror its makeup. Although i like that its shaded in and you can show percentage to keep the shape even as Dail numbers change. Im going to make Google Fusion Time Series, a Timeplot and Tableau Public version. I think Timeplot will do the job best but take longer. Come back later.
In response to my tweets was pointed to two other similar Dail Charts.
House A very well made java applet(made in 2006) which shows the make up of Dail since 1918, its shows a colored bar chart, government parties, majorities and seats loses and gains, which you can play in a slideshow.
guthanphobail.net An Irish language page with stats and charts back to 1982 and the latest referendums. Very detailed java charts showing counts and transfer of the all the candidates not just the winners.
Next the rate of change of tds over the years, that'll take some work...
