Using ChartFX i Delphi 2

Hi
First time on the newsgroup.

I have problems in using the ChartFX component from OCX.
I like to make a minor program to visualize a temperature PID regulation
and therefore some kind of a chart is nessary. I try to use the ChartFX
object but it seem very complexed. First of all i like to know how to put
data into the chart - good start I think !
If anyone have some examples I would be very greatful.

My knowledge of delphi is related to small programs for mechanical
devolepment help.
Best regards Claus
