Tiny Graphs

In the discussion of climate change, a lot of people show a lot of graphs. I’m probably one of the more prolific blog graphers myself. There’s one fault with graphs which I think sabotages their very purpose: creating a plot in which the y-axis is so small that all the variation is squeezed into a tiny space. This makes variation a lot harder to see, which is rather nonsensical since the real purpose of graphs is usually to make the changes which are present visible.
