如果我错了，请纠正我，但我猜你正在使用.Net Framework的Microsoft图表控件，你的问题不是很清楚。

无论如何，您可以使用工具提示显示鼠标悬停点的值。
Chart1.Series("Series1").ToolTip = "#VALX - #VALY"
这将在您悬停的点的工具提示中显示X值和Y值。

代码示例（visual basic）：

' Creating the series
Dim series1 As New Series("Series1")

' Setting the Chart Type
series1.ChartType = SeriesChartType.Line

' Adding some points
series1.Points.AddXY(0, 10)
series1.Points.AddXY(1, 15)
series1.Points.AddXY(2, 13)
series1.Points.AddXY(3, 21)
series1.Points.AddXY(4, 9)
series1.Points.AddXY(5, 17)

' Add the series to the chart
Chart1.Series.Add(series1)

' Set the chart's height and width
Chart1.Width = 600
Chart1.Height = 600

' Set the chart's visuals
series1.Color = Drawing.Color.Red
series1.IsXValueIndexed = True

' Setting the X Axis
Chart1.ChartAreas("ChartArea1").AxisX.IsMarginVisible = True
Chart1.ChartAreas("ChartArea1").AxisX.Interval = 1
Chart1.ChartAreas("ChartArea1").AxisX.Maximum = [Double].NaN
Chart1.ChartAreas("ChartArea1").AxisX.Title = "x"
Chart1.ChartAreas("ChartArea1").AxisX.TitleFont = New Font("Sans Serif", 10, FontStyle.Bold)

' Setting the Y Axis
Chart1.ChartAreas("ChartArea1").AxisY.Interval = 2
Chart1.ChartAreas("ChartArea1").AxisY.Maximum = [Double].NaN
Chart1.ChartAreas("ChartArea1").AxisY.Title = "y"
Chart1.ChartAreas("ChartArea1").AxisY.TitleFont = New Font("Sans Serif", 10, FontStyle.Bold)

' Setting the mouse hover (tooltip)
series1.ToolTip = "#VALX - #VALY"

在MS折线图中显示光标悬停在光标上的光标及其值
