Question

我需要在X轴上的Infragistics BarChart中显示负值。如果我使用：

设置它

chtAgingVsDueAmt.Axis.X.RangeMax = SOME_NEGATIVE_VALUE

抛出错误：

消息：传递给函数GetScale消息详细信息的错误参数：
在Infragistics.UltraChart.Core.AnInterval.GetScale（Double xmin，双xmax，Int32 n）at Infragistics.UltraChart.Resources.Appearance.AxisAppearance.SmartAxisTickmarks（IAdvanceAxis 轴）在......

如何在X轴上的Infragistics BarChart中显示负值？

我在NA 11.2.20112.2025。代码背后：

 protected void Page_Load(object sender, EventArgs e)
{

    DataTable dt = new DataTable();
    dt.Columns.Add("year", typeof(string));
    dt.Columns.Add("numUsers", typeof(int));
    dt.Rows.Add(new object[] { "2005", -100 });
    dt.Rows.Add(new object[] { "2006", 160 });
    dt.Rows.Add(new object[] { "2007", -250 });
    dt.Rows.Add(new object[] { "2008", 500 });
    dt.Rows.Add(new object[] { "2009", -860 });
    dt.Rows.Add(new object[] { "2010", 600 });
    UltraChart1.Axis.X.RangeMin = -200;
    UltraChart1.Axis.X.RangeMax = 500;
    UltraChart1.Data.DataSource = dt;
    UltraChart1.ChartType = ChartType.BarChart;
    UltraChart1.Data.DataBind();

}
