Second Axis Quote by Cole Nussbaumer Knaflic
““Don’t show the second y-axis. Instead, label the data points that belong on this axis directly. Pull the graphs apart vertically and have a separate y-axis for each (both along the left) but leverage the same x-axis across both. Figure 2.27 illustrates these options. Figure 2.27 Strategies for avoiding a secondary y-axis””
