WPF编程，曲线控件DynamicDataDisplay的使用方法（五）

以下代码基于0.3版本DLL
此处主要写如何在后台代码中，给曲线设置数据源。其中plotter是控件的名字

方法一：Point

        ObservableDataSource<Point> currentDataFrame = new ObservableDataSource<Point>();
            Point point = new Point(0, 0);
            for (int i = 1; i <= 512; i++)
            {
                point.X = i;
                point.Y = i + 100;
                currentDataFrame.AppendAsync(base.Dispatcher, point);
            }

方法二：CompositeDataSource

            const int N = 1000;
            double[] x = new double[N];
            double[] y = new double[N];

            for (int i = 0; i < N; i++)
            {
                x[i] = i;
                y[i] = i;
            }

            var xDataSource = x.AsXDataSource();
            var yDataSource = y.AsYDataSource();

            CompositeDataSource compositeDataSource = xDataSource.Join(yDataSource);
            plotter.AddLineGraph(compositeDataSource, Colors.Goldenrod, 3, "Sine");

方法三：EnumerableDataSource

            const int N = 100;
            Point[] pts = new Point[N];
            for (int i = 0; i < N; i++)
            {
                double x = i;
                pts[i] = new Point(x, x);
            }
            var ds = new EnumerableDataSource<Point>(pts);
            ds.SetXYMapping(pt => pt);
            plotter.AddLineGraph(ds);

如果是自定义的类

            var ds = new EnumerableDataSource<自定义类>(自定义类列表);
            ds.SetXMapping(x => x.类中的字段);
            ds.SetYMapping(y => y.类中的字段);
            plotter.AddLineGraph(ds, Colors.Green, 2, "Volts");
