Create project

Start Visual Studio and select “FILE -> New -> Project…” to create a new Windows Forms application:

Add references

You need references to the OxyPlot and OxyPlot.WindowsForms assemblies. The easiest way to do this is to right click on the “References” item in the Solution Explorer and select “Manage NuGet Packages…” (this requires that the “NuGet Package Manager” extension is installed):

In the “Manage NuGet packages” dialog, search for “OxyPlot” in the top-right search textbox. Select the “OxyPlot.WindowsForms” package and click install:

You can also use the Package Manager Console to install the package:

PM> Install-Package OxyPlot.WindowsForms

Add a plot view

TODO (add component to toolbox?)

Create the plot model

namespace WindowsFormsApplication1{
    using System;
    using System.Windows.Forms;

    using OxyPlot;
    using OxyPlot.Series;

    public partial class Form1 : Form
    {
        public Form1()
        {
            this.InitializeComponent();
            var myModel = new PlotModel { Title = "Example 1" };
            myModel.Series.Add(new FunctionSeries(Math.Cos, 0, 10, 0.1, "cos(x)"));
            this.plot1.Model = myModel;
        }
    }
}

The application should now look like this:

The source code can be found in the HelloWorld\WindowsFormsApplication1 folder in the documentation-examples repository.

散点图：

var model = new PlotModel { Title = "ScatterSeries" };
var scatterSeries = new ScatterSeries { MarkerType = MarkerType.Circle };
var r = new Random(314);
for (int i = 0; i < 100; i++)
{
var x = r.NextDouble();
var y = r.NextDouble();
var size = r.Next(5, 15);
var colorValue = r.Next(100, 1000);
scatterSeries.Points.Add(new ScatterPoint(x, y, size, colorValue));
}
       model.Series.Add(scatterSeries);
       model.Axes.Add(new LinearColorAxis { Position = AxisPosition.Right, Palette = OxyPalettes.Jet(200) });

       plotView1.Model = model;
