- create a new chart, any metric
- observe that one can't rescale it vertically to be small
enough that the vertical axis ticks/labels look bad / overlap
- add another chart, any metric
- observe that the window rescale minima remain the same, so now one can
squish two charts into the space putatively needed for one
- notice in particular that ticks / labels can easily overlap/mush up
- it seems as though the vertical scale's tick/label geometry (number of
major/minor ticks, labels) is decided once, and the view sticks to that
whether or not the view is ultimately shrunk (so those don't fit).
- OTOH, the horizontal (time axis) scale behaves well with respect to resizing;
intermediate ticks / labels get dropped as necessary
