DataSeries.Set() Conversion to NT8 problems

[ericson]

Hey I could use some help with this conversion NT7 to NT8. I think i added the relevant code. The bold is where I believe Im having problems. Original code is Fx.Set(n,x[1]+sum);

The chart line is incorrect.

protected override void OnStateChange() 
		{ 
		  if (State == State.SetDefaults) 
		  {
			  AddPlot(new Stroke(Brushes.DimGray,2),PlotStyle.Line,"Fx");//Plot0
................................................
for(n=i0;n<=i0+p;n++)
			{
				sum=0;
				for(kk=1;kk<=degree;kk++)
				{
				sum+=x[kk+1]*Math.Pow(n,kk);
				}
				[B]Fx[0] = (x[1]+sum);[/B]
			} 
..............................................
 [Browsable(false)]	// this line prevents the data series from being displayed in the indicator properties dialog, do not remove
        [XmlIgnore()]		// this line ensures that the indicator can be saved/recovered as part of a chart template, do not remove
        public Series<double> Fx
        {
            get { return Values[0]; }
        }

Hello ericson,

Thank you for your note.

Without the full code I’m unable to test on my end.

Is your for loop under OnBarUpdate?

What is incorrect about the chart line?

Have you added print statements to check the values of the line?

I’ve provided a link to a youtube video which covers an example of using prints to understand behavior:

I’ve provided a link covering debugging which you may find helpful.

I look forward to your reply.

Solution is Fx[n] = (x[1]+sum);
