What do these colors in the dive graph (logbook) mean?

[Sipadiver]

this is just the log of the 'testdive', but what do these 2 colored parts mean?

These are the deco ceilings. They are red when you violated the ceiling.

Thanks Matthias,
it would be great to add some scaling to the graph, i mean with numbers. of course the blue lines indicate 10m or 10min (at least in this example), but a few numbers would add to readability.

I don't think it's necessary, reading will be more difficult with numbers on the graph

"the blue lines indicate 10m or 10min (at least in this example)" : not at least, always

I tend to agree with Bardass. I also think the lines are, if anything, indicative. If one wants to see more details of the dives, they should be downloaded to divinglog or jdivelog.
