[R] help on plotting series with different x-axis values on a graph with one x-axis

[John Kane]

No image. png files seem to make it through so if you save as png it should arrive.  

Some sample code and data would help

Is the data in one data.frame or could you put it into one?  If so you might want to try melting the data (see reshape 2 package) and plotting with ggplot2
