我在 VB.net 中有三个列表视图，我想从中获取通用值并从中制作自定义图表例如，例如。

Listview1  Listview2  Listview3
A          B          H
B          C          B
C          A          D
D          E          E
E          J          F

Common in Listview

列表视图中常见

1 And 2    2 And 3   1 And 3
A          B         B
B          E         D
C                    E
E

There is a chart tool where you can add your values and plot in various styles

有一个图表工具，您可以在其中添加值并以各种样式绘制

Here's a simple example of creating a line graph with a single series containing 3 data points.

这是一个简单的示例，该示例使用包含 3 个数据点的单个系列创建折线图。

Drag a chart to your form and add this code

将图表拖到您的表单中并添加此代码

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
     Chart1.Series.Clear()
     Chart1.Titles.Add("Demo")
     'Create a new series and add data points to it.
     Dim s As New Series
     s.Name = "aline"
     'Change to a line graph.
     s.ChartType = SeriesChartType.Line
     s.Points.AddXY("1990", 27)
     s.Points.AddXY("1991", 15)
     s.Points.AddXY("1992", 17)
     'Add the series to the Chart1 control.
     Chart1.Series.Add(s)
 End Sub

You will need to add

你需要添加

Imports System.Windows.Forms.DataVisualization.Charting

Of course you would have to iterate through your data and add points based on your information.

当然，您必须遍历数据并根据您的信息添加点。
