使用Telerik控件库制作WPF项目中的折线图、柱状图、饼图和甜甜圈图

發布時間：2024/1/1 asp.net 35 豆豆

生活随笔收集整理的這篇文章主要介紹了使用Telerik控件库制作WPF项目中的折线图、柱状图、饼图和甜甜圈图小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

本博客是基于 .Net Framework 4.6.2 的WPF（MVVM）項目，Telerik版本為 2016.2.613.40。其他版本是否可用不詳。

本文章所使用數據均為測試數據，無任何意義。

本博客所有內容是根據本人實際使用情況，面向百度及Telerik官方文檔、Telerik官方示例、Telerik官方論壇。如超出需求，可自行查詢。

//引入命名空間 xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" xmlns:chartView="clr-namespace:Telerik.Windows.Controls.ChartView;assembly=Telerik.Windows.Controls.Chart" xmlns:animation="clr-namespace:Management.Control"

Palette可選樣式： https://docs.telerik.com/devtools/wpf/controls/radchartview/features/palettes/introduction

1.折線圖：

1.1 XAML

<telerik:RadCartesianChart Margin="10" Palette="Autumn" TrackBallInfoStyle="{StaticResource trackBallInfoStyle}"> <telerik:RadCartesianChart.HorizontalAxis> <chartView:CategoricalAxis Title="月份" GapLength="0.8" PlotMode="OnTicksPadded" /></telerik:RadCartesianChart.HorizontalAxis><telerik:RadCartesianChart.VerticalAxis> <chartView:LinearAxis Title="案件數量"/></telerik:RadCartesianChart.VerticalAxis><telerik:RadCartesianChart.Grid> <telerik:CartesianChartGrid MajorLinesVisibility="Y" StripLinesVisibility="Y"/></telerik:RadCartesianChart.Grid><telerik:RadCartesianChart.Series><telerik:LineSeries ShowLabels="True" ValueBinding="Number" CategoryBinding="KeyName" animation:ChartAnimationUtilities.CartesianAnimation="DropWithDelay" TrackBallInfoTemplate="{StaticResource consumptionTrackBallInfoTemplate}" ItemsSource="{Binding MonLawcases}"> </telerik:LineSeries></telerik:RadCartesianChart.Series><telerik:RadCartesianChart.Behaviors><telerik:ChartTrackBallBehavior ShowIntersectionPoints="True" />  </telerik:RadCartesianChart.Behaviors></telerik:RadCartesianChart>

1.2 資源樣式

折線圖上鼠標滑過提示的樣式

鼠標滑過數據展示模板

1.3 數據模型

public class LineInfo {public int KeyName { get; set; }public int Number { get; set; } } private ObservableCollection<LineInfo> _monLawcases;public ObservableCollection<LineInfo> MonLawcases{get { return _monLawcases; }set { SetProperty(ref _monLawcases, value, "MonLawcases"); }}

注：SetProperty(ref _monLawcases, value, “MonLawcases”);為Prism框架寫法，可替換為

public class XXX:INotifyPropertyChanged{private ObservableCollection<LineInfo> _monLawcases;public ObservableCollection<LineInfo> MonLawcases{public event PropertyChangedEventHandler PropertyChanged;get { return _monLawcases; }set { _monLawcases= value; if (PropertyChanged != null){ PropertyChanged(this, new PropertyChangedEventArgs("MonLawcases")); } }}}

2.柱狀圖：

2.1 XAML

<telerik:RadCartesianChart Grid.Column="2" Margin="10"HoverMode="FadeOtherSeries"TrackBallInfoStyle="{StaticResource trackBallInfoStyle}" ><telerik:RadCartesianChart.HorizontalAxis><telerik:CategoricalAxis Title="單位名稱" GapLength="0.5"/></telerik:RadCartesianChart.HorizontalAxis><telerik:RadCartesianChart.VerticalAxis><telerik:LinearAxis Title="檢材數量"SmartLabelsMode="SmartStepAndRange"/></telerik:RadCartesianChart.VerticalAxis><telerik:RadCartesianChart.Grid><telerik:CartesianChartGrid MajorLinesVisibility="Y" StripLinesVisibility="Y"/></telerik:RadCartesianChart.Grid><telerik:RadCartesianChart.Behaviors><telerik:ChartTrackBallBehavior /></telerik:RadCartesianChart.Behaviors><telerik:RadCartesianChart.Series><telerik:BarSeries ValueBinding="Count"ShowLabels="True" CategoryBinding="Name" animation:ChartAnimationUtilities.CartesianAnimation="RiseWithDelay" TrackBallInfoTemplate="{StaticResource consumptionTrackBallInfoTemplate1}"ItemsSource="{Binding UnitDevices}"></telerik:BarSeries></telerik:RadCartesianChart.Series></telerik:RadCartesianChart>

public class BarChartParam{public string Name { get; set; }public int Count { get; set; }} private ObservableCollection<BarChartParam> _unitDevices;public ObservableCollection<BarChartParam> UnitDevices{get { return _unitDevices; }set { SetProperty(ref _unitDevices, value, "UnitDevices"); }}

3 餅圖

3.1 XAML

<telerik:RadPieChart Palette="Summer" x:Name="PieChart"><telerik:RadPieChart.SmartLabelsStrategy > <telerik:PieChartSmartLabelsStrategy DisplayMode="SpiderUnaligned"/></telerik:RadPieChart.SmartLabelsStrategy><telerik:RadPieChart.Behaviors><telerik:ChartSelectionBehavior DataPointSelectionMode="Single"/></telerik:RadPieChart.Behaviors><telerik:RadPieChart.Series> <telerik:PieSeries ItemsSource="{Binding UnitDevicePercentage}" animation:ChartAnimationUtilities.PieAnimation="Slice"  ValueBinding="Number"> <telerik:PieSeries.LegendSettings><telerik:DataPointLegendSettings TitleBinding="Name" /></telerik:PieSeries.LegendSettings><telerik:PieSeries.LabelConnectorsSettings><telerik:ChartSeriesLabelConnectorsSettings /></telerik:PieSeries.LabelConnectorsSettings><telerik:PieSeries.LabelDefinitions><telerik:ChartSeriesLabelDefinition Template="{StaticResource PieLableTemplate}"/></telerik:PieSeries.LabelDefinitions></telerik:PieSeries></telerik:RadPieChart.Series> </telerik:RadPieChart> <telerik:RadLegend Grid.Column="1"HorizontalAlignment="Center"VerticalAlignment="Bottom"Items="{Binding LegendItems, ElementName=PieChart}"/>

$標簽注意若使用模板的寫法，數據源需要是計算好的百分比（如 4.45），若不想計算百分比可按代碼中注釋的 LabelFormat寫法，控件庫可自行計算百分比，此時不能使用模板樣式 -------------甜甜圈圖同樣。

$圖例注意綁定的Items 為餅圖的名稱x:Name=“PieChart”。

3.2 資源樣式

//餅圖標簽顯示樣式模板<DataTemplate x:Key="PieLableTemplate"><StackPanel Orientation="Horizontal"><TextBlock Text="{Binding DataItem.Name}"/><TextBlock Text=":"/><TextBlock Text="{Binding DataItem.Number,StringFormat=\{0:n2\}}"/><TextBlock Text="%"/></StackPanel></DataTemplate>

3.3 數據模型

public class PieInfo{public string Name { get; set; }public double Number { get; set; }} private ObservableCollection<PieInfo> _unitDevicePercentage;public ObservableCollection<PieInfo> UnitDevicePercentage{get { return _unitDevicePercentage; }set { SetProperty(ref _unitDevicePercentage, value, "UnitDevicePercentage"); }}
