Best regards,
Kamil

Hi, In teeTree you can make your own shapes and show them in the editor. The shapes in the teeTree library can function as an example, eg TreeUML.pas, TreeTransit.pas.

Changing points color in FastLineSeries
Hi there,
Is there any possibility to change a color of individual points
in FastlineSeries? I tried properties ColorEachPoint,ValueColor and
function Add(x,'',color), but they they don't work and color of point
is still the same . I'm using TeeChart7 under Delphi7.
Thanks for any ideas.
