Polynomial Fitting on Series

Chris.CHWU · Post by **Chris.CHWU** » Thu Oct 09, 2008 9:05 am

Greetings,

I tried to apply poly. fitting on my series but got an exception from the red line bellow. Please help me to solve this problem. Thanks a lot.

fastLine1.Function = polyFitting1

Code: Select all

        Dim series As Steema.TeeChart.Styles.Points = _
          TChart1.Series.Add(New Steema.TeeChart.Styles.Points())
        series.Add(0.0000327429511222184, 217.974565416658)
        series.Add(0.0000449872090402736, 113.620689449038)
        series.Add(0.0000707548748640967, 506.886177999488)

        Dim polyFitting1 As New Steema.TeeChart.Functions.PolyFitting
        Dim fastLine1 As New Steema.TeeChart.Styles.FastLine
        fastLine1.DataSource = series
        fastLine1.VertAxis = series.VertAxis
        polyFitting1.PolyDegree = 3
        fastLine1.Function = polyFitting1
        fastLine1.ShowInLegend = True
        TChart1.Series.Add(fastLine1)

        TChart1.Aspect.View3D = False

Hi Chris,

Thanks for reporting. I could reproduce the issue here and added it (TF02013440) to the defect list to be fixed for next releases.

Dear Sirs,

Can you please tell me what the current state of your implementation is?

Thank you.

Hi Chris,

We have been investigating the issue here and it seems an expected behaviour as an exception handling was added for TF02011495, which is described here:
