Hello Marco,

thanks for your kind reply. Dataframe objects try to mimic vector and
matrix. Starting from the previous example,
plot(t, x(:, 1))
will work as expected, yet both inputs are dataframe objects. Both are
vectors, and values are converted automatically. 

The issue is on 'plot(t, x)': the vector versus matrix paradigm fails. The
version in octave-dataframe-1.0.0-1 will fail early, as there is some bug in
dataframe "bsxfun" implementation. Having solved this bug on the SF
repository, I would like to go further and fix this issue with plotting.
