自定义可左右滑动、拖拽滑动的平面柱状图

 

在做这种样式控件之前，可先浏览我之前预研的控件：

A、

B、

 OK，现在说下控件具体设计过程：

1）采用Grid布局，这样可以将Y轴的标题设置平均高度，X轴的柱子也可以平均。

　　当然X轴也会存在一个问题，当数据较少时，只有俩个柱子难道就布满界面？

　　很简单，在Grid中多添加一个ColumnDefinition就行了，柱子的宽度设置成可配置，额外的一个设置成默认填充。

2）Bar采用RadioButton,因为有Checked属性，之后整个控件SelectionChanged的事件源可以从这来

3）滑动条容器，我这边比较熟悉DevExpress控件，所以用的是ScrollBox，然后修改其中的模板。

其它的一些设置比较简单，就不说了，直接看代码

 

1、UserControl界面

2、UserControl后台

public partial class BarChartControl : UserControl    {        public BarChartControl()        {            InitializeComponent();        }        public Brush BorderBrush        {            get { return (Brush)GetValue(BorderBrushProperty);

       public Thickness BorderThickness        {            get { return (Thickness)GetValue(BorderThicknessProperty); }            set { SetValue(BorderThicknessProperty, value); }        }        public static readonly DependencyProperty BorderThicknessProperty = DependencyProperty.Register("BorderThickness",        typeof(Thickness), typeof(BarChartControl),        new PropertyMetadata(new Thickness(1.0, 0.0, 1.0, 1.0)));
