The Enable 2-Value Axes tool is an important tool when mashing up different data sets with drastically different scales. If I pull one variable of my data into the platform with numbers in the thousands, that’s not going to look very good next to my other variable that is showing me a percentage. For this purpose, we have added the Enable 2-Value Axes feature so that you can still see the different variables on the same metric.
To do so, bring your data series onto the metric, and then click the Enable 2-Value Axes button under Display. You’ll see that the right side and the left side of the metric each have unique scales associated with their data sets. Label your data series and enable the legend so that it is easier to see which graph belongs to which data series.

Charts That Support 2-Value Axes

Note: The plural of axis is axes. It looks weird, like lumberjack style, but it is correct.
