```Hi Vasco,

I just discovered that there exists a possible solution, at least if you
don't have too many states. You can use the "density" and "angle"
standard R options, as in the example below. The "density" argument is
for the density of the lines, you can use either a single value or a
vector with at most one value for each state (in the example I use only
three different densities,which are repeated), and "angle" is for the
angle of the lines, and you can also use either a single value or a
vector as in the example.

You will have to plot the legend separately, by using "withlegend=FALSE"
for seqdplot and then seqlegend with the same "density" and "angle"
arguments

library(TraMineR)

## creating the sequence object

mvad.alphabet <- c("employment", "FE", "HE", "joblessness", "school", "training")
mvad.labels <- c("employment", "further education", "higher education", "joblessness", "school", "training")
mvad.scodes <- c("EM", "FE", "HE", "JL", "SC", "TR")

## Plotting

Best regards,
Alexis
