Hi,

CloneChartSeries function works fine with TChartSeries. e.g.
NewSeries:=CloneChartSeries(Series1);

But same function won't work with TFastLineSeries.

What is the best way to clone TFastLineSeries?

Regards,

Hi odissey1,

You can do something like this:

Code: Select all

procedure TForm1.FormCreate(Sender: TObject);
var MyFastLine: TFastLineSeries;
begin
    Chart1.AddSeries(CloneChartSeries(Series1));
    MyFastLine := (Chart1[Chart1.SeriesCount-1] as TFastLineSeries);
end;

Hi Narcis,

well I´m a little bit speechless

We develope an application which records serial data from chargers. So you have series like voltage and current.
And with our old engine we tought a long long time how to implement a function for curve comparison. And now I found this little piece of code. It solved our long term problem within 10 minutes.

I´m very amazed. Thx !!!!
