如何使用C#实现运行状态堆叠柱状图

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。

界面设计

添加用户控件（窗体）

代码如下

主窗体代码

 public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        private void btn_AddData_Click(object sender, EventArgs e)        {            var bSucessd = sysTimeBarChart1.InitDataList(true);            if (bSucessd)                MessageBox.Show("完成");        }    }
