Aspect ratio II: setting ratios
When values are not on the same scale it can be a bit tricky to set an appropriate aspect ratio. A classic William Cleveland (inventor of dot plots) example is the sunspots
data set. We have 3200 observations from 1750 to 2016.
sun_plot
is a plot without any set aspect ratio. It fills up the graphics device.
To make aspect ratios clear, we've drawn an orange box that is 75 units high and 75 years wide. Using a 1:1 aspect ratio would make the box square. That aspect ratio would make things harder to see the oscillations: it is better to force a wider ratio.
