下午好,现在我有了这张图表,但我想在条形图中添加红色和蓝色线条。我对 oxyplot 很陌生。感谢您的帮助。

我目前正在处理保存为 bool 值的继电器中的事件显示。所以最好有水平线引用。

蓝线只是表示系统中事件的另一条线。

enter image description here

这是我的xaml

<Window x:Class="Label_Issue.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:Label_Issue"
xmlns:oxy="http://oxyplot.org/wpf"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Grid>
<oxy:PlotView x:Name="barChartModel"/>
</Grid>

这是我的.cs

namespace Label_Issue
{

public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();

SetUtilizationData();
}

public PlotModel PlotModel { get; set; }
private void SetUtilizationData()
{
PlotModel = new PlotModel
{

LegendOrientation = LegendOrientation.Vertical,
LegendPlacement = LegendPlacement.Outside,
LegendPosition = LegendPosition.RightTop
};


// define x-axis
OxyPlot.Axes.DateTimeAxis dateAxis = new OxyPlot.Axes.DateTimeAxis
{
Position = OxyPlot.Axes.AxisPosition.Bottom,
//StringFormat = "dd/MM/yy HH:mm" // automatisch?
};

// add to plotmodel.axes
PlotModel.Axes.Add(dateAxis);


// define y-axis
CategoryAxis categoryAxis = new CategoryAxis
{
Position = AxisPosition.Left,
};

//add to plotmodel.axes
PlotModel.Axes.Add(categoryAxis);

IntervalBarSeries barSeries = new OxyPlot.Series.IntervalBarSeries
{
LabelMargin = 0
};

TestData td = new TestData();
for(int index=0; index<10;index++ )
{
IntervalBarItem item = new IntervalBarItem
{

Start = OxyPlot.Axes.DateTimeAxis.ToDouble(new DateTime(2017, 04, 01, 06, 00 + index, 00)),
End = OxyPlot.Axes.DateTimeAxis.ToDouble(new DateTime(2017, 04, 01, 07, 00 + index, 00)),
CategoryIndex = index,
Title = "test"
};
barSeries.Items.Add(item);
}

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

最佳答案

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);
