这是一个看似简单的问题,但我找不到简单的答案。我想为图表上现有的 Y 轴指定最小值和最大值。

这是图表:

<Window x:Class="TempDataAnalyzer.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525" 
    xmlns:chartingToolkit="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit" 
    Loaded="Window_Loaded">
<Grid>
     <chartingToolkit:Chart  Name="lineChart" Title="Temperature" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
        <chartingToolkit:LineSeries  DependentValuePath="Value" IndependentValuePath="Key" ItemsSource="{Binding}" IsSelectionEnabled="True"/>
     </chartingToolkit:Chart>
</Grid>

现在,我在 Y 轴上添加 0 到 71 之间的值:

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

    private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        List<KeyValuePair<int, int>> entries = new List<KeyValuePair<int, int>>();
        entries.Add(new KeyValuePair<int, int>(0, 0));
        entries.Add(new KeyValuePair<int, int>(1, 23));
        entries.Add(new KeyValuePair<int, int>(2, 45));
        entries.Add(new KeyValuePair<int, int>(3, 46));
        entries.Add(new KeyValuePair<int, int>(4, 71));

        lineChart.DataContext = entries;
    }

}

但是,无论我添加什么值,我都希望图表 Y 轴显示 0 到 100 之间的范围。这是为了使其与同一页面上的不同图表保持一致。

在您的声明中添加此XAML代码:Chart

<chartingToolkit:Chart.Axes>
    <chartingToolkit:LinearAxis Orientation="Y" Minimum="0" Maximum="100"/>
</chartingToolkit:Chart.Axes>
