WPF 自定义柱状图 BarChart

WPF 自定义柱状图 

当前的Telerik控件、DevExpress控件在图表控件方面做得不错，但是有时项目中需要特定的样式，不是只通过修改图表的模板和样式就能实现的。

或者说，通过修改当前的第三方控件以达到项目中UI的界面效果，花费的时间远比重新自定义一个控件要长得多！

所以直接自定义柱状图吧~下面是柱状图的效果：

1、新建一个UserControl，在界面上添加一些简单的布局

<UserControl x:Class="WpfApplication11.BarChartControl"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
            xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
            mc:Ignorable="d" 
            d:DesignHeight="100" d:DesignWidth="200" Loaded="BarChartControl_OnLoaded">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="*"></RowDefinition>
            <RowDefinition Height="Auto"></RowDefinition>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto"></ColumnDefinition>
            <ColumnDefinition Width="*"></ColumnDefinition>
            <ColumnDefinition Width="Auto"></ColumnDefinition>
        </Grid.ColumnDefinitions>
        <Grid x:Name="HeaderGrid" Grid.Row="0" Grid.Column="1" Height="20">
        </Grid>

        <Grid x:Name="LeftGrid" Grid.Row="1" Grid.Column="0">
        </Grid>
        <Border x:Name="MainBorder" Grid.Row="1" Grid.Column="1" BorderThickness="2,0,2,0" BorderBrush="Black">
        </Border>
        <Grid x:Name="MainGridForRow1" Grid.Row="1" Grid.Column="1">

        </Grid>
        <Grid x:Name="MainGridFrom0To1" Grid.Row="0" Grid.Column="1" Grid.RowSpan="2">

        </Grid>
        <Grid x:Name="RightGrid" Grid.Row="1" Grid.Column="2">
        </Grid>

        <Grid x:Name="BottomGrid" Grid.Row="2" Grid.Column="1">
        </Grid>
    </Grid>
</UserControl>

2、UserControl的后台界面

通过添加一些依赖属性，然后在后台生成界面。也可以把柱状替换成RadioButton，实现柱状图选择，添加选择事件的委托方法。

 /// <summary>
    /// BarChartControl.xaml 的交互逻辑
    /// </summary>
    public partial class BarChartControl : UserControl
    {
        public BarChartControl()
        {
            InitializeComponent();
        }

        public Brush BorderBrush
        {
            get { return (Brush)GetValue(BorderBrushProperty); }
            set { SetValue(BorderBrushProperty, value); }
        }

        public Thickness BorderThickness
        {

        public AxisYModel AxisY
        {

            set { SetValue(AxisYProperty, value); }
        }

        public static readonly DependencyProperty AxisYProperty = DependencyProperty.Register("AxisY",
        typeof(AxisYModel), typeof(BarChartControl),
        new PropertyMetadata(new AxisYModel()));

        public AxisXModel AxisX
        {
            get { return (AxisXModel)GetValue(AxisXProperty); }
            set { SetValue(AxisXProperty, value); }
        }

        public static readonly DependencyProperty AxisXProperty = DependencyProperty.Register("AxisX",
        typeof(AxisXModel), typeof(BarChartControl),
        new PropertyMetadata(new AxisXModel()));
        public double HeaderHeight
        {
            get { return (double)GetValue(HeaderHeightProperty); }
            set { SetValue(HeaderHeightProperty, value); }
        }
        public static readonly DependencyProperty HeaderHeightProperty = DependencyProperty.Register("HeaderHeight",
        typeof(double), typeof(BarChartControl), new PropertyMetadata(10.0));
        public string Header
        {
            get { return (string)GetValue(HeaderProperty); }
            set { SetValue(HeaderProperty, value); }
        }
        public static readonly DependencyProperty HeaderProperty = DependencyProperty.Register("Header",
        typeof(string), typeof(BarChartControl), new PropertyMetadata());

        private void BarChartControl_OnLoaded(object sender, RoutedEventArgs e)
        {

            LeftGrid.Width = AxisY.Width;

            SetYTitlesContent();

            SetXDatasContent();
        }

        private void SetXDatasContent()
        {
            var axisXModel = AxisX;

            {
                int count = axisXModel.Datas.Count;
                for (int i = 0; i < count + 1; i++)
                {
                    BottomGrid.ColumnDefinitions.Add(new ColumnDefinition());
