c# - 在x坐标等于0的序列中绘制点

当您有一个所有x坐标均为零的线系列时，图表将有助于重新组织点，以便x坐标为1、2、3等。这很好，但是，在我只有一个点的情况下在系列中，该点的x坐标确实为零，我想覆盖这种“有用的”行为，以使该点以其真实的x坐标（即0.0）而不是替代的x坐标（即1.0）。

有谁知道如何做到这一点？我怀疑这是显而易见的。

谢谢jstreet。您的示例就是我想要的，但是当我运行这段代码时，我得到了这个输出！有什么不同？

void MainFormLoad(object sender, EventArgs e)
{
    Random r = new Random();
    chart1.Series["Series1"].ChartType= SeriesChartType.Line;
    chart1.Series["Series1"].IsXValueIndexed= false;

    chart1.Series["Series2"].ChartType= SeriesChartType.FastLine;
    chart1.Series["Series2"].IsXValueIndexed= false;

    chart1.Series["Series3"].ChartType= SeriesChartType.Point;
    chart1.Series["Series3"].IsXValueIndexed= false;

    chart1.Series["Series4"].ChartType= SeriesChartType.FastPoint;
    chart1.Series["Series4"].IsXValueIndexed= false;

    chart1.Series["Series5"].ChartType= SeriesChartType.Line;
    chart1.Series["Series5"].IsXValueIndexed= true;

    chart1.Series["Series6"].ChartType= SeriesChartType.FastLine;
    chart1.Series["Series6"].IsXValueIndexed= true;

    chart1.Series["Series7"].ChartType= SeriesChartType.Point;
    chart1.Series["Series7"].IsXValueIndexed= true;

    chart1.Series["Series8"].ChartType= SeriesChartType.FastPoint;
    chart1.Series["Series8"].IsXValueIndexed= true;

    for (int i = 0; i < 10; i++)
    {
        chart1.Series["Series1"].Points.AddXY(0, r.Next(70, 80));
        chart1.Series["Series2"].Points.AddXY(0, r.Next(60, 70));
        chart1.Series["Series3"].Points.AddXY(0, r.Next(50, 60));
        chart1.Series["Series4"].Points.AddXY(0, r.Next(40, 50));
        chart1.Series["Series5"].Points.AddXY(0, r.Next(30, 40));
        chart1.Series["Series6"].Points.AddXY(0, r.Next(20, 30));
        chart1.Series["Series7"].Points.AddXY(0, r.Next(10, 20));
        chart1.Series["Series8"].Points.AddXY(0, r.Next(0, 10));
    }
}

最佳答案

AddXY始终尊重您的意愿。如果您使所有点x = 0，那么您将得到：

    private void Form1_Load(object sender, EventArgs e)
    {
        Random r = new Random();

        for (int i = 0; i < 10; i++)
            chart1.Series["Series1"].Points.AddXY(i, r.Next(0, 50));

        for (int i = 0; i < 10; i++)
            chart1.Series["Series2"].Points.AddXY(0, r.Next(50, 100));

        chart1.Series["Series3"].Points.AddXY(0, 0);
    }
