First of all you need to have input suitable to work with. Only then
you can massage the available data to look like you want.
In order to come up with a maximum of 24 hours starting and ending at
10:00 UTC, you could experiment with a number of CDEFs.
perhaps with some protection against unknown data, such as:
or something alike (I am not testing this, debug as necessary).
Labels on top of areas are AFAIK not possible. Remember that RRDtool is
designed to show many samples on one image, not just 24 or even 1.
400 labels on top of 400 lines would be unreadable.
You want an answer? You'd better follow the following guidelines!
Linesize well below 80 chars. Reply to the list, not to me. Trim
irrelevant lines. Answer below the remaining paragraph.
