下午好,现在我有了这张图表,但我想在条形图中添加红线和蓝线。我非常喜欢与oxyplot。谢谢你的帮助。
我目前正在处理保存为布尔值的继电器中的事件显示。所以有一个水平线参考会很好。
蓝线只是代表系统中事件的另一条线。

这是我的.cs

private void SetUtilizationData()

OxyPlot.Axes.DateTimeAxis dateAxis = new OxyPlot.Axes.DateTimeAxis

PlotModel.Axes.Add(categoryAxis);

TestData td = new TestData();

CategoryIndex = index,
Title = "test"

barSeries.Items.Add(item);
}
PlotModel.Series.Add(barSeries);
barChartModel.Model = PlotModel;
}
}

对于其他人:
using OxyPlot.Annotations;
double X = 0.0D;
double Y = 0.87825D;
LineAnnotation Line = new LineAnnotation()
{
StrokeThickness = 1,
Color = OxyColors.Green,
Type = LineAnnotationType.Horizontal,
Text = (Y).ToString(),
TextColor = OxyColors.White,
X = X,
Y = Y
};
myPlotViewModel.Annotations.Add(Line);
答案 1 :(得分:1)
我使用Plotmodel.LineAannotation创建了垂直线,并在Y轴中创建了带有majorgridlinestyle的水平线,但也可以使用线注释来完成。
