Hi,
I have run into this problem a couple of times now and hope you can help!
If I want to plot mulitiple series with differing x-axis values (however, all in the same range) in 1 plot with one common axis R obstruses the plots.
E.g. if I plot water content against time and I start with the sampler at 5 cm depth, it plots that one right.
But the next depth, 15 cm, is measured at slightly different time intervals and so R will not plot the series correctly.
Reading in the data using “ stringsAsFactors=FALSE” helps, but the lines are still plottet in an akward fashion (edgy) , see attached image.
Hope you can help!
