Oxyplot Plotmodel High AxisTickLabel 对于多个 Y 轴不完全可读

Question

我正在尝试调整 Y 轴之间的距离，以便用户可以阅读整个 AxisTickLabel。 有没有我可以使用的属性或其他东西？

我的 PlotModel 看起来像这样：

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);

作为用户，您可以从给定的 3 个轴中选择要查看的轴。 对于较高的 TickLabelValues >1000，这些值在到达下一个 Y 轴时很难读取。

PositionTier 是您要查找的属性。这是我用来创建该图像的代码：

        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"
        });
