Monitor graphs - 2 x BW if Area selected



  • I'm running latest image:
    2.4.0-BETA (amd64)
    built on Sat Jul 01 21:47:06 CDT 2017
    FreeBSD 11.0-RELEASE-p10

    And playing with Status->Monitoring , and see 4Mb/s utilization if i use graph Lines (seems correct).
    If i switch the graph to Area the utilization doubles , as if the "out total" it self is added to the out.

    Is that a "feature" or "bug" , or me totally missing the concept here ?

    See attached images

    TIA
