Here's an image I made in paint on what I'm trying to do
Basically I'm trying to plot years on the major x axis and months on the minor x axis. And every three months (March, June,September,December) have a vertical broken line. I have really no clue where to start.
I'm not even sure if it is possible. I'm not sure if Hadley was addressing a similar question here. Some wrote "
Impossible labeling the minor ticks: Is this justified or a conceptual bug. At first sight it seems obvious that you want to do that, for example Mayor=years minor=months" and hadley responded
There is an infinite number of things that seems "obvious" to someone - I can only implement and support a finite number
...so I'm not sure if what I want to do is possible in ggplot2.
