    I just returned from holidays, which is why I didn't respond earlier.

    Could you send me a data set and program that does what you say it does:
    i.e. plot fine for bars, but not for hbars? I will then have a look at
    what this could be.

    If you could also send me a set that is "relatively the same" but
    doesn't show this problem, that'd be much appreciated.

    Thanks,
    Martien

    PS. I won't have access to my regular email account until Monday, and I
    have quite some work to catch up with, so don't expect a speedy reply.
