在X轴上的inffragistics柱状图中显示负值

本文关键字：显示 inffragistics | 更新日期: 2023-09-27 18:16:07

我需要在X轴的inffragistics BarChart中显示负值。如果我使用:

chtAgingVsDueAmt.Axis.X。RangeMax = SOME_NEGATIVE_VALUE

抛出错误:

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

如何在X轴上显示inffragistics条形图中的负值?

在X轴上的inffragistics柱状图中显示负值

我与NA 11.2.20112.2025。背后的代码:

 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();
}
