篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了WPF 自定义BarChartControl（可左右滑动的柱状图）（转）相关的知识，希望对你有一定的参考价值。
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：
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
