The first bit of advice would be to include the unsuccessful code that used geom_path. Otherwise we hav no way of knowing what you gave as the grouping argument. The second bit of advice would be to include a dataset that illustrates the problem. (These are both bits of advice that you should have found in the Posting Guide.
