If your values are strings, then they are strings and not dates, and therefore the axis will be discrete, and not continuous dates. The one exception is string values that are formatted like the Date constructor but without the "new " prefix. E.g. "Date(2018, 5, 10)"
Note, again, that month indices in the Date constructor and this string notation start with 0, so 5 is actually June, not May.
