Axes ticks should be more appropriately spaced

[djbarnwal]

For a set of time ranges, generate an axis at a bunch of breakpoints. Each one of those breakpoints should look good & provide the info we need.

A PR should have -

• a dev route that has a bunch of standalone data graphics with just an axis.
• each one will have a different width. Let’s have 3 breakpoints
• We cycle through a bunch of time ranges generating these graphs
• then we visually compare to see where the axis breaks down

Does this issue refer to the x-axis or to both x- and y- axes?

With multiple measures, I'm running into a situation where the y-axis ticks are confusing. The y=0 tick could be mistaken for the y=max tick in the graph below it. See especially the bottom graph here:
