在图表控件上显示两组数据点？

Question

我正在尝试使用图表控件来显示折线图中两个单独项目之间的差异。

每个项目都有一个二维数组，如下所示：

double[,] a = { {1, 2}, {4, 5} };

如何将每个数组添加为Chart控件上的单独序列？

多亏了艾哈迈德（Ahmed）给我的文档，我才得以弄清楚。

我正在写我如何设法使它工作，以防像我这样的人无法将头放在图表控件周围。 他们让我有些困惑。

我使用两个单独的系列数据填充图表的最简单方法是：

// set chart
Chart compareChart = dropoffChartForm.dropoffDamageChart;

// set chart basics
compareChart.Series.Clear(); // clear existing series
compareChart.ChartAreas[0].AxisX.Interval = 10.0; // interval of striplines
compareChart.ChartAreas[0].AxisX.Minimum = 0; // minimum of X axis
compareChart.ChartAreas[0].AxisX.Maximum = 100; // maximum of X axis
compareChart.ChartAreas[0].AxisX.Title = "Meters"; // title of X axis
compareChart.ChartAreas[0].AxisY.Title = "Damage per Bullet"; // title of Y axis

// add A series
compareChart.Series.Add(A.name);
compareChart.Series[A.name].Points.DataBindXY(A.pointsX, A.pointsY);
compareChart.Series[A.name].ChartType = SeriesChartType.Line; // set type to line chart
compareChart.Series[A.name].Color = Color.Red;

// only add B series if it differs from A series
if (A.name != B.name) {
    compareChart.Series.Add(B.name);
    compareChart.Series[B.name].Points.DataBindXY(B.pointsX, B.pointsY); // each of these is a simple array of 4 doubles
    compareChart.Series[B.name].ChartType = SeriesChartType.Line; // set type to line chart
    compareChart.Series[B.name].Color = Color.Blue;
}

compareChart.Update(); // update chart after adding data
