I want to have the capabilities like Steema TeeChart's Arrow Series,
is there a built-in way of doing that or an example?  And if not, what
would the best approach to writing it be, a Field Series?

I have never worked with TeeChart's Arrow Series, but looking at
screenshots indicates that our TFieldSeries might come close. See the
documentation in https://wiki.lazarus.freepascal.org/TAChart_documenta
tion#Field_series. You need a two-valued x and y chart source, the
first data point is for the center of the arrow, the second for the
arrow direction. There is an example in folder
(lazarus)/components/tachart/demo/multi, page "Field".
