小编给大家分享一下如何使用C#实现运行状态堆叠柱状图，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
具体内容如下
需求通过柱状图显示设备运行时间停止时间，稼动率等
通过数据库查询记录，按小时显示显示目标数据。
添加用户控件（窗体）
代码如下
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Windows.Forms; using System.Windows.Forms.DataVisualization.Charting; namespace TestRunChart { public partial class SysTimeBarChart : UserControl { public List<SysTimeCnt> ListAllTime=new List<SysTimeCnt>(); public SysTimeBarChart() { InitializeComponent(); this.chart1.Series.Clear(); } public DateTime timeStart { get{ DateTime Time1 = this.dateTimePickerLast.Value; DateTime Time2 = this.dateTimePickerStart.Value; return Time1 >= Time2?
