Thank you Alex.
The "transparency" problem is solved.
:-)
//off-topic: May be it is a good idea to add a description of colour
format (rrggbbTT) in the RRD documentation.
I'll continue to look for a solution for UTF-8 encoding.
Best Regards,
George Andonov

Sorry, can't help.
2. How to add "transparency" to the area?
Quote from the documentation:
... Additionally you can add an alpha channel (transparency). The
default will be ``FF'' which means non-transparent. ...
Please provide some examples.
AREA:somevalue#FF0000:red
AREA:somevalue#FF0000FF:red
AREA:somevalue#FF000080:transparent_red
AREA:somevalue#FF000000:invisible
These numbers are hexadecimal.
Colors are RGBT or RRGGBBTT, where R or RR describes the amount of
red, G and B similar for green and blue. T or TT describes how solid
a color is: 0x00 is completely see-through, 0x80 is half see-through,
0xFF is completely solid and nothing shines through.
If only one digit per color is used, then the possible values
are 0 1 2 3 4 5 6 7 8 9 A B C D E F.
If two digits are used, 00 01 02 03 .. 0e 0f 10 11 12 .. 1e 1f 20 21..
2e 2f...3f...4f...fe ff.
