async/await, no results

[Bogopo]

I thought I'd read about async/await as I'd said, and that's what it was.

On the basis of several examples, the code block was completed

static Task<double> getresulting(int frc,int frc1,double shag,double U,double T)
        {
            int t = 0;
            double resulting = 0;
            NumericalIntegration integration = new NumericalIntegration();
            return Task.Run(() =>
            {
               resulting = (1 / (2 * Math.PI)) * integration.Calculate(angularFrequency =&gt; GetSpectralDensityOfAmplitude(GetSpectralDensity(U, angularFrequency, T)) * Math.Cos(angularFrequency * t), 0, frc1);
            return resulting;
        });
    }

Then the method from which I've been slowing it all down has made it async-method.
And I will. static Task<double> getresulting

In the line double resulting = await getresulting(frc, frc1, shag, U, T);

I do what I'm supposed to do.

public async void drawreverse(double U, double T, double shag, int frc, int frc1)

{

GraphPane panel77 = zedGraphControl2.GraphPane;

//NumericalIntegration integration = new NumericalIntegration();

//double t = 0;

panel77.Title.Text = "Обратное преобразование";

panel77.XAxis.MajorGrid.IsVisible = true;

panel77.YAxis.MajorGrid.IsVisible = true;

panel77.YAxis.MajorGrid.IsZeroLine = false;

panel77.XAxis.Title.Text = "f,кГЦ";

panel77.YAxis.Title.Text = "U(f), мВ*с";

PointPairList list1 = new PointPairList();

        for (double fr = frc; fr <= frc1; fr += shag)
        {
          double resulting = await getresulting(frc, frc1, shag, U, T);
            list1.Add(fr, resulting);
        }

        panel77.AddCurve("", list1, Color.Blue, SymbolType.None);

        panel77.XAxis.Scale.Min = xmin_limit;
        panel77.XAxis.Scale.Max = xmax_limit;

        panel77.YAxis.Scale.Min = ymin_limit;
        panel77.YAxis.Scale.Max = ymax_limit;

        zedGraphControl2.AxisChange();
        zedGraphControl2.Invalidate();
    }

The program is compiled and operated, but it doesn't work on ZedGraphControl2.

I don't clean it because it's filled with points, and I assumed I'd call task getresulting at every step and put a point at the coordinates.

The problem is you don't get anything between the calculation of the parts. You've got one point of result that's going to come into. list1♪ And only after all the work is done list1 It's a schedule. If you want to be updated after each counted point, add the data to zedGraphControl2 after each cycle iteration.
