Is it possible to display a serie without interpolation? lazarus / 55-TAChart ---------------------------------------------------------------------- stab · 2015-06-02 15:43 I wonder if it is possible to display a data serie without having it interpolated to a smooth curve? I need to see raw data as I'm interpreting CNC profiles. Regards stab ---------------------------------------------------------------------- wp · 2015-06-02 15:50 I assume that you are talking about TLineSeries: - ShowPoints := true; - LineType := ltNone; If this does not answer your question: please be more specific. ---------------------------------------------------------------------- stab · 2015-06-02 16:25 Thanks alot, Your answer solved my problems. Stupidly enough I had used B-spline series. /stab
