使用c#在MSChart中显示serie的特定方法

2023年2月18日 161次阅读

我想知道是否有任何方法可以显示这个系列如下,图表类型是列.

我知道我需要一个(X,Y)对来显示图中的数据点,但问题是我需要在x的范围内显示Y值,为了澄清这一点,让我们举一个例子：

X轴显示小时和Y轴产量值,在这种情况下,生产从7:30开始,所以从7:30到8,产量比如20个单位;从8-9,660个单位; 9-10,45个单位和10-10：35 18个单位.

我可以用MSChart,或者你们建议我的任何其他人来实现这一目标吗？这是一个winform应用程序.

谢谢

最佳答案 您应该查看
MS Chart site.“下载”选项卡包含WinForms示例,您可以将其作为WinForms项目下载,在Visual Studio中运行,并查看所需图表的代码.图表控件包含在.Net 4中,但可​​以下载并添加为.Net 3.5的参考.

你想要的是柱形图.您可以在图表上将值设置为系列,然后可以选择列的宽度以显示所需的x值范围.

基本思想是创建Chart,ChartArea和Series,以及可选的Title和Legend.

您将一个或多个Series对象添加到ChartArea,然后将ChartArea,Title和Legend添加到图表中.

您可以单独向系列添加DataPoints,如下例所示,或者将Chart.DataSource设置为类似于DataTable的类并使用DataBinding.

这是柱形图示例中的一个片段：

System.Windows.Forms.DataVisualization.Charting.Chart chart1 = new System.Windows.Forms.DataVisualization.Charting.Chart();
System.Windows.Forms.DataVisualization.Charting.ChartArea chartArea1 = new System.Windows.Forms.DataVisualization.Charting.ChartArea();
