1. Is it possible to set the line width of a TLineSeries?

2. With a number of TLineSeries, each with a Z value, what variables
are set to construct a 3D plot?

I'd really appreciate it if you don't tell me to check the demos.

Yes, of course. Did it not work for you?

I do not understand the question.

Can I add a question if I remove one of your?
1: the line width can be set in the TLineSeries.LinePen.Width.  it can
also be set useing the object inspector

now for my question:
#3 I'm in need of a chart recorder like graph.  I've expearmented and
found it's best for me to clr the line and reload it each time so the
auto scale and axit continue to act on just the last 10 seconds (3000
pts)of data.  I'm just about to write an object that crops the data
and updates the lineSeires but I whated to verify I'm Not reinventing
the wheel.  My be this is done automaticly if I use the "Source" field
or some other feature??

Did you try to user-defined series?
