The formula does not take space between the parts into account. More refined control can be achieved by providing a dash tuple (offset, (on_off_seq)).For example, (0, (3, 10, 1, 15)) means (3pt line, 10pt space, 1pt line, 15pt space) with no offset, while (5, (10, 3)), means (10pt line, 3pt space), but skip the first 5pt line.
