c# – 指定WPF图表的最小和最大轴

这是一个看似简单的问题,但我找不到简单的答案.我想在图表上指定现有Y轴的最小值和最大值.

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,我希望图表Y轴显示0到100之间的范围,无论我添加什么值.这是为了使它与同一页面上的不同图表保持一致.

解决方法 在Chart声明中添加此XAML代码: <chartingToolkit:Chart.Axes> <chartingToolkit:LinearAxis Orientation=”Y” Minimum=”0″ Maximum=”100″/></chartingToolkit:Chart.Axes>
