Dueling Y-Axes

An interesting reading about fanciness and pointlessness of displaying data.

The team at OmniGraphSketcher wrote about the display of multiple y-scales overlaid on the same graph, to make it possible to plot several different types of related data on the same chart. I do this too in TrailRunner but my solution targets the middle of what they call a bad idea and what they suggest as a realistic solution.

The main conclusion of the OmniGraphSketcher team is that overlaying data with disparate scales saves space, but it makes the data significantly harder to interpret. The dual axes “duel” for your attention. So instead of overlaying scales, [they] recommend using a set of multiple graphs, aligned along their common axis.
