[R] GGPLOT2 Different Layers Different X Values

Hello Hadley,

I'm not sure how easily I'd be able to come up with a good example. My data contain thousands of points, and I can't really divulge this data outside my company. But I can tell you that I found a solution (though somewhat hackish). I just created another matrix with each date having a single value. I then added that as a separate histogram scaled to something ridiculously small (like 0.0001). It acts as a sort of place holder for all the other layers. It seems to do that job.

Hi John,

Could you please provide a small reproducible example?
