There are two ways to use oxyplot.dll to draw plot as you want:

  • C# Code Dealing
  • WPF XAML Dealing

C# Code Dealing

Advantages：灵活自定义、绘制效率高 Steps as following:

1、定义PlotModel

var plotModel = new PlotModel
{
  Title = "",
  LegendPosition = LegendPosition.TopLeft,
  LegendPlacement = LegendPlacement.Outside,
  LegendItemAlignment = HorizontalAlignment.Left,
  LegendOrientation = LegendOrientation.Horizontal,
  DefaultFont = ConstantValues.DefaultFont,
  DefaultFontSize = ConstantValues.DefaultFontSize
};

2、定义轴LinearAxis

var xAxis = new LinearAxis
{
  Position = AxisPosition.Bottom,
  Key = "x",
  MajorGridlineStyle = LineStyle.Solid
};

3、将轴添加到PlotModel中

plotModel.Axes.Add(xAxis);

4、创建（线条）数据

var  lineSeries = new LineSeries
{
  Title = line.Title,
  XAxisKey = xAxis.Key,
  YAxisKey = i.ToString(),
  Color = OxyColor.Parse(line.Color.ToString()),
  LineStyle = line.LineStyle,
  TrackerFormatString = "{0}\n{1}:{2}\n{3}:{4:0.00}"
};

5、将线条添加到PlotModel中

lineSeries.Points.AddRange(line.Points.Select(p =>new DataPoint(p.X,p.Y)));
plotModels.Series.Add(lineSeries);

WPF XAML Dealing

Advantages：简单方便、类实时绘制
