How to Access correctly to Positions Property in a LinePlot with Ilnumerics?

Question

i would like to access to the coordinate information in a LinePlot, i wanto to use the Property LinePlot.Positions as show in the following code:

using System;
using System.Collections.Generic;
using System.Text;
using ILNumerics.Data;
using ILNumerics.Drawing.Plotting;
using ILNumerics.Drawing;
using ILNumerics;
using static ILNumerics.ILMath;
using System.Linq;

namespace TestConsoleUI2
{
    class Program
    {
        static void Main(string[] args)

         {
            Array<double> xx = linspace(10, 15, 5);
            Array<double> yy = linspace(8, 90, 5);

            LinePlot myLinePlot = new LinePlot(xx, yy);

            RetArray<float> p = myLinePlot.Positions;

          }
    }
}

Nevertheless i got an System.NullReferenceException i have debugged and the data exists at that moment, can anyone help me?

Regards

Can you create [minimal reproducible example](https://stackoverflow.com/help/minimal-reproducible-example)? — Prasad Telkikar, Aug 18 '20 at 12:27
From that single line of code, it is impossible to find the cause of your problem. Either dividedDataSets or LinePlot is null. Or if they are properties, some object that is used in the getter is null. — SomeBody, Aug 18 '20 at 12:33
sorry i just wanted to keep it simple, i just tested the edit coded and still bring the Exception @PrasadTelkikar SomeBody — DonMiguelSanchez, Aug 18 '20 at 13:17

using System.Text;
using ILNumerics.Data;
using ILNumerics.Drawing.Plotting;
using ILNumerics.Drawing;
using ILNumerics;
using static ILNumerics.ILMath;
using System.Linq;

namespace TestConsoleUI2
{
    class Program
    {
        static void Main(string[] args)

         {
            Array<double> xx = linspace(10, 15, 5);
            Array<double> yy = linspace(8, 90, 5);

            LinePlot myLinePlot = new LinePlot(xx, yy);

            PositionsBuffer p = myLinePlot.Line.Positions;

          }
    }
}
