Hello Yu,
It is possible to display bars below the line by giving them negative
values. You could try making all of your negative strand values be
negative, which would separate them from your positive strands.
However, any overlapping entries will not display properly.
Unfortunately, there is no way of avoiding that, so you may have more
luck using two separate displays.
Sorry for the inconvenience, and best of luck. Please contact us
again if you have other questions.
Best
