### How to plot lattice paths ?

I have seen that the command

for D in DyckWords(n): D.pretty_print(type="NE-SE")

gives a nice plot of all Dyck paths.

Is there an analogous command for the set of all 2^n lattice paths of length n with up- and downsteps of height 1? Please give details, I am a newcomer to SAGE.

Edit: Sorry, if my question is not properly formulated. Perhaps I should modify my question somewhat: The command

D=DyckWords(6)[3]

D.pretty_print(type="NE-SE")

gives a nice picture (which I unfortunately cannot copy)

of the Dyckpath corresponding to [1, 0, 1, 0, 1, 0, 1, 1, 0, 1, 0, 0]

by interpreting 0 with a down-step and 1 with an up-step.

How can I print a corresponding picture for a word which corresponds to a path with negative values?
