在X軸上的Infragistics BarChart中顯示負值

我需要在X軸上的Infragistics BarChart中顯示負值。如果我把它用：在X軸上的Infragistics BarChart中顯示負值

chtAgingVsDueAmt.Axis.X.RangeMax = SOME_NEGATIVE_VALUE

它拋出錯誤：

Message: Bad arguments passed to function GetScale Message Details:
at Infragistics.UltraChart.Core.AnInterval.GetScale(Double xmin, Double xmax, Int32 n) at Infragistics.UltraChart.Resources.Appearance.AxisAppearance.SmartAxisTickmarks(IAdvanceAxis axis) at ...

我怎麼能顯示在X軸中的Infragistics BARCHART負值？

什麼是X軸'RangeMin'設置爲？ – AakashM

我還沒有設定。我相信當值爲負時，我需要設置RangeMin，否則設置RangeMax。這有意義嗎？ –

我相當肯定你需要設置它們兩個，並且你需要確保'RangeMin'小於'RangeMax'。我懷疑給你錯誤的是'RangeMin'仍然是它的默認值（可能爲零），並且你將'RangeMax'設置爲小於'RangeMin'，這是不允許的。 – AakashM

我與NA 11.2.20112.2025。後面的代碼：

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(); 

}
