c# 使用 Oxyplot 创建和绘制 ContourSeries

我有一个 WPF 应用程序，我需要在其中可视化 y = y(x1, x2)，其中 x1、x2 是线性坐标。我可以使用 Oxyplot 中的 HeatMapSeries 来做到这一点，但是当我想在同一窗口中绘制两组数据时，热图不是合适的工具。几个轮廓系列会更好。现在，我尝试以与 HeatMapSeries 相同的方式实现这一点，效果非常好:

<span style="color:#212529"><span style="background-color:#c1e6c6"><span style="color:#212529"><code style="margin-left:2px"><span style="color:#000000">public</span> <span style="color:#000000">void</span> <span style="color:#000000">PlotHeatMap</span> (){OxyPlot.PlotModel model = <span style="color:#000000">new</span> PlotModel { Title = <span style="color:#000000">"2-D data"</span> };model.Axes.Add( <span style="color:#000000">new</span> OxyPlot.Axes.LinearColorAxis { Position = OxyPlot.Axes.AxisPosition.Right, Palette = OxyPalettes.Jet( <span style="color:#ae7313">500</span> ), HighColor = OxyColors.Gray, LowColor = OxyColors.Black } );OxyPlot.Series.HeatMapSeries heatmap = <span style="color:#000000">new</span> OxyPlot.Series.HeatMapSeries {Data = ( Double[ , ] )data,X0 = x1min,X1 = x1max,Y0 = x2min,Y1 = x2max};model.Series.Add( heatmap );
}
</code></span></span></span>

Output from the HeatMapSeries

现在，当我尝试改用 ContourSeries 时，我只是将 HeatMapSeries 替换为 ContourSeries:

<span style="color:#212529"><span style="background-color:#c1e6c6"><span style="color:#212529"><code style="margin-left:2px"><span style="color:#000000">public</span> <span style="color:#000000">void</span> <span style="color:#000000">PlotContour</span> (){OxyPlot.PlotModel model = <span style="color:#000000">new</span> PlotModel { Title = <span style="color:#000000">"2-D data"</span> };model.Axes.Add( <span style="color:#000000">new</span> OxyPlot.Axes.LinearColorAxis { Position = OxyPlot.Axes.AxisPosition.Right, Palette = OxyPalettes.Jet( <span style="color:#ae7313">500</span> ), HighColor = OxyColors.Gray, LowColor = OxyColors.Black } );OxyPlot.Series.ContourSeries contour = <span style="color:#000000">new</span> OxyPlot.Series.ContourSeries {ColumnCoordinates = arrayFromMinToMax1,RowCoordinates = arrayFromMinToMax2,ContourLevels = arrayOfLevels,ContourColors = arrayOfColors, <span style="color:#6c6b5a">// Same # elements as the levels' array</span>Data = ( Double[ , ] )data};model.Series.Add( contour );
}
</code></span></span></span>

这只会产生输出:
