Placing lines on TChart

[Tore Fossum]

How can one put a line horizontal and a line
vertical on a Teechart line plot? these lines
are markers for an inflection point in an
s curve.

The tee chart could be a data aware or
non data aware.

Many thanks for any hints.

Hi Tore,

here is an example to draw a vertical line at xvalue from minimum to
maximum left axis values:

with Chart2 do
begin
Canvas.MoveTo (BottomAxis.CalcXPosValue(xvalue),
LeftAxis.CalcYPosValue(LeftAxis.Minimum));
Canvas.LineTo (BottomAxis.CalcXPosValue(xvalue),
LeftAxis.CalcYPosValue(LeftAxis.Maximum));
end;

Regards,

Rolf Fankhauser

The latest Ver 5 has a ColorLine Tool which can be optionally dragged
by a mouse.
