Agreed, but that visualization is even worse because it lacks a y-axis scale entirely.
- disgruntledphd2 5y agoOne of the things I learned as a megacorp data scientist is that you should always remove the scales on the y-axis in anything vaguely public, because of the risk of material information leak. (Think about user growth as a particularly good example of a variable like this).
- amarshall 5y agoIf absolute values are a concern then why not replace the unit with % change? One could, assuming linear scale, reverse engineer that onto this plot anyway. Some plots, of course, might stand better on their own without a y-axis scale (histogram distribution probably). To be honest, this plot is pretty useless either way; who cares about the trend it took downward since we have little or no context on what happened at any given point?
