File talk:UK general election polling over a period of 25 years.png

So I'm thoroughly confused by both this graph and the other one (polling since 2010), because the time spacing doesn't seem to be consistent? The gap between what seems to be the 2001 and 2005 elections is tiny, while 2010-2015 takes up half the screen. Is this deliberate? And if it is, can it not be? It's confusing for time graphs to be unevenly spaced, especially if it's not labeled as such. Thanks! Chuborno (talk) 21:23, 12 July 2017 (UTC)
