Oxyplot- WPF: Adding data from a List of double to DataPoint - wpf

Question

I am new to WPF and the project I'm working on requires me to plot a list of double on XY chart. I added Oxyplot to my project for the charting but I'm having challenges to get a plot.
I followed the example on Oxyplot site (see code below), but I discovered that the DataPoint can only accept double values of x and y not array or list of doubles.
How can I plot List<double> for XValues and List<double> for YValues?
namespace WpfApplication2
{
using System.Collections.Generic;
using OxyPlot;
public class MainViewModel
{
public MainViewModel()
{
this.Title = "Example 2";
this.Points = new List<DataPoint>
{
new DataPoint(0, 4),
new DataPoint(10, 13),
new DataPoint(20, 15),
new DataPoint(30, 16),
new DataPoint(40, 12),
new DataPoint(50, 12)
};
}
public string Title { get; private set; }
public IList<DataPoint> Points { get; private set; }
}
}

I really don't see why you cannot directly store a list of DataPoint... but let's say you're stucked with your 2 lists and I'm assuming that your lists have same length (if not you have an issue since all points to draw should have an X and Y value).
So I guess something like that:
List<double> XValues = new List<double> { 0, 5, 10, 22, 30 };
List<double> YValues = new List<double> { 2, 11, 4, 15, 20 };
for (int i = 0; i < XValues.Count; ++i)
{
Points.Add(new DataPoint(XValues[i], YValues[i]));
}
It's not really elegant and if you are the one creating the lists you should merge them into a list of DataPoint like said #PaoloGo. If you prefer to use a custom object in case you don't use oxyplot, you can create a simple one like that for example:
public struct ChartPoint
{
public double X;
public double Y;
public ChartPoint(double x, double y)
{
X = x;
Y = y;
}
}
And then you store this:
List<ChartPoint> points;
