OxyPlot sum 系列

Question

我有一个带有两个 LineSeries 的 Oxyplot 图表，我想添加一个新 LineSeries，它是两个原始 LineSeries 的总和。

如何创建 Sum LineSeries？

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        var myModel = new PlotModel { Title = "Example 1" };
        myModel.Series.Add(new FunctionSeries(function1, 0, 100, 0.1, "a*1"));
        myModel.Series.Add(new FunctionSeries(function2, 0, 100, 0.1, "b*2"));

        this.plotView1.Model = myModel;
    }

    public double function1(double a)
    {
        double result = 0;
        result = a * 1;
        return result;
    }

    public double function2(double b)
    {
        double result = 0;
        result = b * 2;
        return result;
    }
}

Answer 1

好吧，你只需要创建另一个函数：

public double function3(double b)
{
   return function1(b) + function2(b);
}

然后

myModel.Series.Add(new FunctionSeries(function3, 0, 100, 0.1, "a+b*2"));
