Is there a way to display axis tick marks using one measurement but display labels based on a different measurement?
I have been asked to plot a Kaplan-Meier curve with the x-axis showing tick marks as weeks but labeling in months. This is not as simple as assuming that a month has exactly 4 weeks. I am using the formula: MONTHS=(WEEKS*7)/30.4375. Thus, 8 weeks will not appear as 2 months but rather 1.84 months. In other words, my labels will be slightly off of my tick marks as I attempt to display below:
