使用 c# 在 MSChart 中显示系列的特定方法

Question

不知道有没有办法把这个serie显示如下，chartype是column。

我知道我需要一个 (X,Y) 对来显示图表中的数据点，但问题是我需要在 x 范围内显示一个 Y 值，为了澄清这一点，让我们放一个示例：

X 轴显示小时数和 Y 轴生产值，在这种情况下，生产从 7:30 开始，所以从 7:30 到 8 点的生产假设为 20 个单位； 8-9，60个单位； 9-10, 45 个单位，10-10:35 18 个单位。

我可以使用 MSChart 或者你们建议的其他任何一种来实现吗？这是一个 winform 应用程序。

谢谢

你应该看看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。

您想要的是柱形图。您将值设置为图表上的系列，然后您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Chart。

您将DataPoints 单独添加到Series，如下例所示，或者您将Chart.DataSource 设置为DataTable 之类的东西并使用DataBinding。

这是来自柱形图示例的 sn-p：
