thanks a lot, this is clear now; If I understand you correctly, to get the expected factors, I need to modify my series (add xmin to all x, add ymin to all y), before using AnswerVector ? Or is there another method/property I could use to get directly the coefficients used to draw the polynom (the p...

Hi Narcis, sorry for the late reply. To get the coefficient factors, we use the TCurveFittingFunction and AnswerVector. I have made another simple test case, which unfortunately I cannot ship because it uses some internal classes. Here is the description of my test, which you should be able to repro...

Wrong correlation coefficient
We use TeeChartPro V7 in Borland c++ builder.
On a graph, we display the correlation function, which is a polynom
of degree 1 (f(x)=ax + b
The graph is correct.
The coefficient for degree 1 is correct.
The coefficient for degree 0 is INCORRECT.
We use AnswerMethod to get the coefficients.

No ParentChart to validate datasource
Following code worked ok in BorlandC++ with TeeChartPro5
FCorrSeries = new TLineSeries(Chart);
FCorrSeries->DataSources->Clear();
FCorrSeries->DataSources->Add(FChartSeries);
In TeeChartPro7, we have error:
No ParentChart to validate datasource
Any idea ?
