    Strange effect in stacked graphs

    Hi.
    I'm seeing something strange in some of my stacked graphs. This is graph that stacks data from snmp traffic oids.
    When looking at a large period of time, the graph looks normal. Attached file 24_hr.png (The first image) (don't mind the gap at the end, that's the server being shutdown).

    If I look at the same data, but with 12 hours, the last image is shown. This is also the case with less time. There is no gaps in the data that I can find, so it is the image generation.

    Does anyone have a suggestion to what could be causing this?
