asp.net - 为什么标签在 ASP.NET 图表中消失？

Question

Chart1 显示了所有标签，但是一旦我添加了第 10 项，一半的标签就会消失。

首先是标记:

    <asp:Chart ID="Chart1" runat="server" Width="700" Height="600">
        <series>
            <asp:Series Name="Series1" ChartType="Bar" />
        </series>
        <chartareas>
            <asp:ChartArea Name="ChartArea1" />
        </chartareas>
    </asp:Chart>

    <asp:Chart ID="Chart2" runat="server" Width="700" Height="600">
        <series>
            <asp:Series Name="Series1" ChartType="Bar" />
        </series>
        <chartareas>
            <asp:ChartArea Name="ChartArea1"/>
        </chartareas>
    </asp:Chart>

我们添加一些数据...

    Dim labels As New System.Collections.Generic.Dictionary(Of String, Integer)

    labels.Add("1 thing", 24655)
    labels.Add("2 thing", 11355)
    labels.Add("3 thing", 6890)
    labels.Add("4 thing", 5815)
    labels.Add("5 thing", 5155)
    labels.Add("6 thing", 4160)
    labels.Add("7 thing", 2430)
    labels.Add("8 thing", 2055)
    labels.Add("9 thing", 1545)


    Chart1.Series("Series1").Points.DataBindXY(labels, "Key", labels, "Value")
    Chart1.DataBind()

    labels.Add("10 thing", 1530)

    Chart2.Series("Series1").Points.DataBindXY(labels, "Key", labels, "Value")
    Chart2.DataBind()

Answer 1

我只需要将轴的间隔设置为

Chart2.ChartAreas("ChartArea1").AxisX.Interval = 1
