Alex Velez shows how we can work with a particular case of problem:
Today’s post is about a common challenge: when one data series is so large relative to the others that a single scale makes it nearly impossible to see any details. Consider the following line graph. It displays state and local revenue by transportation mode, which I created using data from the Bureau of Transportation Statistics 2018 Report.
Alex has one solution. Another idea could be to change the Y axis to log scale, especially because you’re dealing with money. That would tighten up the series and allow for more information to be displayed on the single graph.
