  We investigate self-similar scalar field solutions to the Einstein equations
in whole cylinder symmetry. Imposing self-similarity on the spacetime gives
rise to a set of single variable functions describing the metric. Furthermore,
it is shown that the scalar field is dependent on a single unknown function of
the same variable and that the scalar field potential has exponential form. The
Einstein equations then take the form of a set of ODEs. Self-similarity also
gives rise to a singularity at the scaling origin. We extend the work of [1],
which determined the global structure of all solutions in the causal past of
the singularity. We identified a class of solutions that evolves through the
past null cone of the singularity. We give the global structure of these
solutions and show that the singularity is censored in all cases.
