Question

我有一个工作的DLL，我有一个函数将数组添加到列表中，另一个函数显示ZED图形图中的所有列表数组。所有阵列都具有相同的大小。目前，x轴以0到1024的点显示。问题是：我需要更改什么才能及时显示x轴？

我有值“Intervall”（两点之间的时间），我可以传入函数。

感谢您的帮助。

这是我到目前为止所拥有的：

public void AddGraph(double[] Values, string LegendName)
{
    int i = 0;
    PointPairList list = new PointPairList();
    for (i = 0; i < Values.Length; i++)
    {
        list.Add(i, Values[i]);
    }

    if (i > MaxXAxis)
        MaxXAxis = i;

    SList.Add(list);
    SListColor.Add(Color.Black);
    SListName.Add(LegendName);
}

public void ShowDiagram(string Title, string XAxisName, string YAxisName, int Timeout_ms)
{     
    ZedGraph.ZedGraphControl zgc = new ZedGraphControl();
    GraphPane myPane = zgc.GraphPane;
    LineItem myCurve = null;


    // Set the titles and axis labels
    myPane.Title.Text = Title;
    myPane.XAxis.Title.Text = XAxisName;
    myPane.YAxis.Title.Text = YAxisName;

    for (int i = 0; i < SList.Count(); i++)
    {
        myCurve = myPane.AddCurve(SListName[i], SList[i], SListColor[i], SymbolType.None);
        myCurve.Line.Width = 2;
    }

    // Add gridlines to the plot, and make them gray
    myPane.XAxis.MinorGrid.IsVisible = true;
    myPane.YAxis.MinorGrid.IsVisible = true;
    myPane.XAxis.MinorGrid.Color = Color.LightGray;
    myPane.YAxis.MinorGrid.Color = Color.LightGray;
    myPane.XAxis.MinorGrid.DashOff = 0;
    myPane.YAxis.MinorGrid.DashOff = 0;

    myPane.XAxis.MajorGrid.IsVisible = true;
    myPane.YAxis.MajorGrid.IsVisible = true;
    myPane.XAxis.MajorGrid.Color = Color.Gray;
    myPane.YAxis.MajorGrid.Color = Color.Gray;
    myPane.XAxis.MajorGrid.DashOff = 0;
    myPane.YAxis.MajorGrid.DashOff = 0;

    // Move Legend to buttom
    myPane.Legend.Position = LegendPos.Bottom;

    zgc.AxisChange();

    myPane.XAxis.Scale.Max = MaxXAxis;

    zgc.Location = new Point(0, 0);
    zgc.Size = new Size(panel_diagramm.ClientRectangle.Width, panel_diagramm.ClientRectangle.Height);

    panel_diagramm.Controls.Add(zgc);             
}

这是我第一次发帖，所以我为没有把它放在更好的格式而道歉。以下允许您设置x轴以显示时间：

myPane.XAxis.Type = AxisType.Date;
myPane.XAxis.Title.Text = "Time (HH:MM:SS)";
myPane.XAxis.Scale.Format = "HH:mm:ss";
myPane.XAxis.Scale.MajorUnit = DateUnit.Minute;
myPane.XAxis.Scale.MinorUnit = DateUnit.Minute;
myPane.XAxis.Scale.Min = DateTime.Now.Subtract(new TimeSpan(0, 0, 10, 0, 0).ToOADate();
myPane.XAxis.Scale.Max = DateTime.Now.ToOADate();

ZedGraph - 如何从一个点到另一个时间改变X轴？
