TeeChart的X軸為時間，多個Y軸的顯示

 

最后上代碼

public partial class Test : Form
    {
        private TChart tChart = new TChart();
        private int space = 3;

        public Test()
        {
            InitializeComponent();
            Init();
        }

        /// <summary>
        /// 添加若干個自定義坐標軸
        /// </summary>
        /// <param name="count"></param>
        private void AddCustomAxis(int count)
        {
            List<BaseLine> listBaseLine = new List<BaseLine>();
            for (int i = 0; i < tChart.Series.Count; i++)
            {
                listBaseLine.Add((BaseLine)tChart.Series[i]);
            }

            double single = (100 - space * (count + 2)) / (count + 1);//單個坐標軸的百分比
            tChart.Axes.Left.StartPosition = space;
            tChart.Axes.Left.EndPosition = tChart.Axes.Left.EndPosition = tChart.Axes.Left.StartPosition + single;
            tChart.Axes.Left.StartEndPositionUnits = PositionUnits.Percent;
            listBaseLine[0].CustomVertAxis = tChart.Axes.Left;

            double startPosition = tChart.Axes.Left.StartPosition;
            double endPosition = tChart.Axes.Left.EndPosition;
            Axis axis;
            for (int i = 0; i < count; i++)
            {
                axis = new Axis();
                startPosition = endPosition + space;
                endPosition = startPosition + single;
                axis.StartPosition = startPosition;
                axis.EndPosition = endPosition;
                tChart.Axes.Custom.Add(axis);
                listBaseLine[i + 1].CustomVertAxis = axis;
            }
        }

        private void Init()
        {
            tChart.Dock = DockStyle.Fill;
            tChart.Aspect.View3D = false;
            tChart.Legend.LegendStyle = LegendStyles.Series;
            tChart.Axes.Bottom.Labels.DateTimeFormat = "yyyy-MM-dd HH:mm:ss";
            tChart.Axes.Bottom.Labels.ExactDateTime = true;
            tChart.Axes.Bottom.Labels.Angle = 90;
            tChart.Axes.Bottom.Minimum = 12 * Utils.GetDateTimeStep(DateTimeSteps.OneSecond);
            tChart.Axes.Bottom.Minimum = 60 * Utils.GetDateTimeStep(DateTimeSteps.OneSecond);
            panel2.Controls.Add(tChart);

            DataSet data = HSQueryHistoryCurve.Instance.Search(new HSQueryCondition()
            {
                ChannelId = new List<int>() { 1,2,3,4},
                DeviceId = "112233445566",
                StartTime = DateTime.Now.AddMonths(-1).ToString("yyyy-MM-dd HH:mm:ss"),
                EndTime = DateTime.Now.AddMonths(1).ToString("yyyy-MM-dd HH:mm:ss"),
                ProjectId = 1
            });

            DateTime time = DateTime.Now;
            for (int j = 0; j < data.Tables.Count; j++)
            {
                DataTable dataTable = data.Tables[j];
                Line line = new Line();
                tChart.Series.Add(line);
                line.Title = string.Format("曲線{0}", j + 1);
                line.XValues.DateTime = true;
                for (int i = 0; i < dataTable.Rows.Count; i++)
                {
                    line.Add(time.AddSeconds(i).ToOADate(), (double)dataTable.Rows[i][1]);
                }
            }

            AddCustomAxis(3);
        }
    }

 ps：data是一個數據集，包含若干個數據表

每一個數據表對應一條曲線的數據，第一列為時間，第二列為數據。

這里的時間，直接從Datetime.Now重新處理的,僅僅使用了數據表中的第二列數據

 

 

需要注意的是:

必須使用控件本身的縱軸Left，縱軸的刻度才能正常顯示。

如果多個縱軸，全部設置為自定義的。會導致無法正常顯示。

 

獲取所有可見曲線，添加到一個集合中返回

private List<BaseLine> GetVisibleSeries()
        {
            List<BaseLine> visibleSeries = new List<BaseLine>();
            for (int i = 0; i < zbmChart.Series.Count; i++)
            {
                zbmChart.Series[i].CustomVertAxis = null;
                if (zbmChart.Series[i].Visible)
                {
                    visibleSeries.Add((BaseLine)zbmChart.Series[i]);
                }
            }
            return visibleSeries;
        }

 

添加自定義縱軸

private void AddVisibleLineVerticalAxis()
        {
            List<BaseLine> visibleSeries = GetVisibleSeries();

            zbmChart.ClearCustomAxis();//清除所有自定義的坐標軸

            double singleAxisLengthPercent;//單個縱軸占據的百分比

            //計算每個坐標軸占據的百分比
            if (visibleSeries.Count < 1)
            {
                return;
            }
            else
            {
                singleAxisLengthPercent = Convert.ToDouble(100 - verticalAxisSpace * (visibleSeries.Count + 1)) / (visibleSeries.Count);
            }

            //給可見的曲線加上縱軸
            for (int i = 0; i < visibleSeries.Count; i++)
            {
                Series s = visibleSeries[i];
                Axis axis;

                //設置縱軸的起始位置
                if (i == 0)
                {
                    axis = zbmChart.zbmYAxis;
                    axis.StartPosition = verticalAxisSpace;
                }
                else
                {
                    axis = new Axis(false, false, zbmChart.Chart);
                    if (i == 1)
                    {
                        axis.StartPosition = zbmChart.zbmYAxis.EndPosition + verticalAxisSpace;
                    }
                    else
                    {
                        axis.StartPosition = visibleSeries[i - 1].CustomVertAxis.EndPosition + verticalAxisSpace;
                    }
                }
                //設置縱軸的結束位置
                axis.EndPosition = axis.StartPosition + singleAxisLengthPercent;
                //設置縱軸刻度的顏色
                axis.Labels.Font.Color = dicColor[s.Tag.ToString()];

                //設置網格的可見性以及顏色
                axis.Grid.Visible = VisibleSettings.Default.Grid;
                axis.Grid.Color = ColorSettings.Default.Grid;

                if (i == 0)
                {
                    //曲線本身的縱軸，無需額外處理
                }
                else
                {
                    //將自定義縱軸加入圖表
                    zbmChart.AddCustomAxis(axis);
                    //將縱軸和對應的曲線關聯
                    s.CustomVertAxis = axis;
                }
            }
        }
