Question

我可以像回答here一样使用IsAxisVisible = false删除坐标轴，但是当我这样做时就不能再平移或缩放图形了。

图形无法平移的示例代码：

    public class MainViewModel
    {
        public MainViewModel()
        {
            var tmp = new PlotModel { Title = "Simple example", Subtitle = "using OxyPlot" };

            tmp.Axes.Add(new LinearAxis()
            {
                Position = AxisPosition.Bottom,
                IsAxisVisible = false
            });

            tmp.Axes.Add(new LinearAxis()
            {
                Position = AxisPosition.Left,
                IsAxisVisible = false
            });

            var series1 = new LineSeries { Title = "Series 1", MarkerType = MarkerType.Circle };
            series1.Points.Add(new DataPoint(0, 0));
            series1.Points.Add(new DataPoint(10, 18));
            series1.Points.Add(new DataPoint(20, 12));
            series1.Points.Add(new DataPoint(30, 8));
            series1.Points.Add(new DataPoint(40, 15));

            tmp.Series.Add(series1);

            this.Model = tmp;
        }
        public PlotModel Model { get; private set; }
    }

    </Window.DataContext>
    <Grid>
        <oxy:PlotView Model="{Binding Model}" />
    </Grid>
</Window>

xaml.cs

    public partial class MainWindow
    {
        public MainWindow()
        {
            this.InitializeComponent();
        }
   }

如前面的评论中所述，此行为似乎是在Oxyplot 2.0上发生的，而1.0确实允许缩放/平移，即使在轴不可见时也是如此。

另一种方法是将AxislineColor，TextColor和TicklineColor设置为OxyColors.Transparent。

tmp.Axes.Add(new LinearAxis()
{
    Position = AxisPosition.Bottom,
    IsZoomEnabled = true,
    IsPanEnabled = true,
    AxislineColor = OxyColors.Transparent,
    TextColor = OxyColors.Transparent,
    TicklineColor = OxyColors.Transparent
}); ; ;

tmp.Axes.Add(new LinearAxis()
{
    Position = AxisPosition.Left,
    IsZoomEnabled = true,
    IsPanEnabled = true,
    AxislineColor = OxyColors.Transparent,
    TextColor = OxyColors.Transparent,
    TicklineColor = OxyColors.Transparent
});

这将允许您在不显示轴的情况下进行缩放/平移。

Answer 2

我已经确定的解决方案（至少在解决原始问题中描述的IsAxisVisible = false问题之前）是实现Anu的答案，并增加了：

Model.PlotMargins = new OxyThickness(0);

隐藏轴粗度。

如何从Oxplot图形中删除轴，但保留缩放和平移功能？
