我想在 C# 和 VB.NET 中得到建议

我创建了如下图所示的图表：

替代文字

  1. 如何从代码隐藏中自定义每列顶部的值？而不是显示 21, 49, 19 我想显示 21 hr, 49 hr, 19 hr

  2. 如何在其他行之上显示这些值？如您所见，19 位于 Line 系列下方。

  3. 我可以设置在图表区域上画线而不仅仅是在列上吗？因此，这条线将从 X 轴开始到图表区域的末端。

这是标记：

                        </asp:Series>
                    </series>

                        <asp:ChartArea Name="ChartArea1" BorderColor="64, 64, 64, 64" BorderDashStyle="Solid" BackSecondaryColor="White" BackColor="64, 165, 191, 228" ShadowColor="Transparent" BackGradientStyle="TopBottom">

                            <axisy linecolor="64, 64, 64, 64">
                                <labelstyle font="Trebuchet MS, 8.25pt, style=Bold" />
                                <majorgrid linecolor="64, 64, 64, 64" />
                            </axisy>
                            <axisx linecolor="64, 64, 64, 64">
                                <labelstyle font="Trebuchet MS, 8.25pt, style=Bold" />
                                <majorgrid linecolor="64, 64, 64, 64" />
                            </axisx>
                        </asp:ChartArea>
                    </chartareas>
                </asp:chart>

这是代码隐藏：

Chart1.ChartAreas("ChartArea1").AxisX.Interval = 1

    ' Create new data series and set its visual attributes
    Dim series As New Series("Minimum Hour")

    series.ChartType = SeriesChartType.Line
    series.BorderWidth = 2
    series.ShadowOffset = 1
    series.AxisLabel = 0


    Dim monthyHour = 22
    series.Name = "Min. Hour : " & monthyHour

    Dim xValue() As String = {"Jun", "Jul", "Aug"}
    Dim yValue() As Integer = {21, 49, 19}

    'add value for Line series
    For i = 0 To xValue.Length - 1 Step 1

         series.Points.AddY(monthyHour)

    Next

    Chart1.Series(0).Points.DataBindXY(xValue, yValue)

    ' Add series into the chart's series collection
    Chart1.Series.Add(Series)

要从后面的代码添加它，您需要设置 Chart1.Series(0).Label=monthyHour +"Hrs"
