Oxyplot Plotmodel High AxisTickLabel 不能完全讀取多個 Y 軸

Question

我試圖調整 Y 軸之間的距離，以便用戶可以讀取整個 AxisTickLabel。 有財產或我可以使用的東西嗎？

我的 PlotModel 看起來像這樣：

C＃ ：

  Plot = new PlotModel
  {
    Padding = new OxyThickness(0),
    DefaultColors = new List<OxyColor>
    {
      ColorPosition,
      ColorVelocity,
      ColorAcceleration
    },

    LegendOrientation = LegendOrientation.Vertical,
    LegendPlacement = LegendPlacement.Inside,
    LegendPosition = LegendPosition.TopRight,
    LegendBackground = OxyColor.FromAColor(200, OxyColors.White),
    LegendBorder = OxyColors.Black,
    PlotType = PlotType.XY
  };

  // YAxes
  _axisPosition = new LinearAxis
  {
    AxislineColor = ColorPosition,
    TicklineColor = ColorPosition,
    TextColor = ColorPosition,
    AxisTickToLabelDistance = 0,
    Position = AxisPosition.Left,
    Key = "position"
  };
  Plot.Axes.Add(_axisPosition);
  _seriesPosition = new LineSeries
  {
    Title = (string)converter.Convert(new object[] {"", "MotionProfilePosition"}, null, null, CultureInfo.CurrentCulture) + " [" + UnitItemPosition.ToString() + "]",
    YAxisKey = "position"

  };
  Plot.Series.Add(_seriesPosition);

  _axisVelocity = new LinearAxis
  {
    AxislineColor = ColorVelocity,
    TicklineColor = ColorVelocity,
    AxisTickToLabelDistance = 0,
    Position = AxisPosition.Left,
    TextColor = ColorVelocity,
    Key = "velocity"
  };
  Plot.Axes.Add(_axisVelocity);
  _seriesVelocity = new LineSeries
  {
    Title = (string)converter.Convert(new object[] {"", "MotionProfileVelocity"}, null, null, CultureInfo.CurrentCulture) + " [" + UnitItemVelocity.ToString() + "]",
    YAxisKey = "velocity"
  };
  Plot.Series.Add(_seriesVelocity);

  _axisAcceleration = new LinearAxis
  {
    AxislineColor = ColorAcceleration,
    TextColor = ColorAcceleration,
    AxisTickToLabelDistance = 0,
    Position = AxisPosition.Left,
    Key = "acceleration"
  };
  Plot.Axes.Add(_axisAcceleration);
  _seriesAcceleration = new LineSeries
  {
    Title = (string)converter.Convert(new object[] {"", "MotionProfileAcceleration"}, null, null, CultureInfo.CurrentCulture) + " [" + UnitItemAcceleration.ToString() + "]",
    YAxisKey = "acceleration"
  };
  Plot.Series.Add(_seriesAcceleration);


  // XAxis
  _axisTime = new LinearAxis
  {
    Position = AxisPosition.Bottom,
    Key = "time",
    Unit = UnitItemTime
  };
  Plot.Axes.Add(_axisTime);

作為用戶，您可以從給定的 3 個軸中選擇您想要查看的軸。對於更高的 TickLabelValues >1000，這些值在到達下一個 Y 軸時難以讀取。

PositionTier 是您正在尋找的屬性。 這是我用來創建該圖像的代碼：

        PlotModel = new PlotModel();

        PlotModel.Axes.Add(new LinearAxis
        {
            Position = AxisPosition.Left,
            Title = "First",
            Minimum = 0,
            Maximum = 10000
        }) ;

        PlotModel.Axes.Add(new LinearAxis
        {
            Position = AxisPosition.Left,
            Title = "Second",
            Minimum = 0,
            Maximum = 10000,
            PositionTier = 1
        });

        PlotModel.Axes.Add(new LinearAxis
        {
            Position = AxisPosition.Left,
            Title = "Third",
            Minimum = 0,
            Maximum = 10000,
            PositionTier = 2
        });

        PlotModel.Axes.Add(new LinearAxis
        {
            Position = AxisPosition.Bottom,
            Title = "x"
        });
