[Orca-users] Help a newbie out

be

positive

operat-

Thanks for the help!
It's working now, but i still have some questions about orca.
I'll give you my config and the data it's loading to lookat.
data file is /tmp/attempt1.txt

Config is mta.cfg

#REQUIRED OPTIONS

I'm not able to get the color to change, or to get the graph to fill with
the line_type AREA option.
Also my y_legend isn't displaying the current data. It's displaying what i
had specified earlier.

Any ideas on what i'm doing wrong?
Sorry about being a pest.
:)
