【Chart控件】DotNetProjects.DataVisualization.Toolkit 控件库

WPF没有系统的Chart控件，因此要使用第三方的chart控件库

DataVisualization.Toolkit Chart控件结构

 

 

 

 

 

 

 

 

 

 

Chart控件库功能

1、在Nuget中添加DotNetProjects.DataVisualization.Toolkit。
System.Windows.Controls.DataVisualization.Charting

在System.Windows.Controls.DataVisualization.Charting空间下可以定义下面7种图形
1、LineSeries 线性图
2、PieSeries 饼图
3、ColumnSeries 柱形图
4、AreaSeries 区域图
5、BarSeries 条状图
6、ScatterSeries 散点图
7、BubbleSeries 气泡图

8、Stacked Series(栈序列图)

 Chart功能介绍

(1)图例设置

 <!--表格的LegEnd 隐藏图例-->
            <chart:Chart.LegendStyle>
                <Style TargetType="visualizationToolkit:Legend">
                    <Setter Property="Visibility" Value="Collapsed"/>
                    <Setter Property="Width" Value="0"/>
                    <Setter Property="Height" Value="0"/>
                </Style>
            </chart:Chart.LegendStyle>

(2)绘图区设置

   <!--表格的绘图区域  将绘图区背景色设置为透明 -->
            <chart:Chart.PlotAreaStyle>
                <Style TargetType="Grid">
                    <Setter Property="Panel.Background" Value="Transparent"/>
                </Style>
            </chart:Chart.PlotAreaStyle>

(3)标题区设置

      <!--表格的标题 设置标题，默认为null-->
            <chart:Chart.Title >
                饼状图 Demo
            </chart:Chart.Title>

(4)坐标轴 区设置

  
    <!--表格的坐标轴 设置-->
            <chart:Chart.Axes>
                <chart:LinearAxis Orientation="X" Interval="1" Title="次数"></chart:LinearAxis>
                <chart:LinearAxis Orientation="Y" Interval="0.5" Title="高度"></chart:LinearAxis>
            </chart:Chart.Axes>

 

(5)设置色板Palette

Background背景属性可以是画刷或者纯色
 <!--饼状图的调色板 使用共同的Key表示一组色块-->
            <chart:Chart.Palette>
                <datavis:ResourceDictionaryCollection>

                    <ResourceDictionary>

(6)表格的序列设置

 xaml

 <!--表格的序列-->
            <chart:PieSeries ItemsSource="{Binding}"
                    DependentValuePath="Value"
                  
                    IndependentValuePath="Key"
                    Title="Pet Preference" IsSelectionEnabled="True">

            </chart:PieSeries>

C#代码

 public MainWindow()
        {
            InitializeComponent();
          
            chart1.DataContext = new KeyValuePair<string, int>[] {

                                    new KeyValuePair<string, int>("Dog", 30),

                                    new KeyValuePair<string, int>("Cat", 25),

                                    new KeyValuePair<string, int>("Rat", 5),

                                    new KeyValuePair<string, int>("Hampster", 8),

                                    new KeyValuePair<string, int>("Rabbit", 12) };
        }
