Problem with Smoothing function

[johnnix]

Hello,

I am using the latest 2015 version and it looks like the smoothing function does not perform any more when working with TPoint series? Attached is a simple example, if I click the button I get a strange straight line only.

Hello,

Could you please tell us with what TeeChart version this sample behaves different?
Thanks in advance.

Hello,

I am using the latest TeeChart 2015.14.150120. If I use another series type like Line series it works ok.

Hello,

Try this:

Code: Select all

type
  TSeriesAccess=class(TChartSeries);

procedure TForm1.Button1Click(Sender: TObject);
begin
TSeriesAccess(Chart6[1]).SetHorizontal;
 Chart6[1].FillSampleValues(20);
 teefunction1.ReCalculate;
end;

Hello Yeray,

Thank you very much for looking into this. I implemented your suggestion in my app and it works ok but I need to ask, is this a temporary fix or this is by design the way point series should be used with smoothing function?

Hello johnnix,

This is by design. TPointSeries is a vertical series while, in your example, you are using a THorizLineSeries, which is a horizontal series. Given that, you need to make the point series to be horizontal so it can work with an horizontal line series.
