Hi guys,

I'm trying to display in the ultrachart a set of data, so I decided to use a histogram chart type. I relied on this example

http://help.infragistics.com/Help/NetAdvantage/NET/2008.2/CLR2.0/html/Chart_Working_with_Histogram_Chart_Data.html

That example works fine but when I try with my own data, the bars do not appear only the gauss bell (See attached)

why is this happening?

Is there something that I'm  doing  wrong?

Here is my code

Imports Infragistics.UltraChart.Shared.Styles
Imports Infragistics.Win.UltraWinChart
Imports System.Data.SqlClient

Public Class HistorialChart
    Private Sub HistorialChart_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim ultraChart1 As New UltraChart
        Me.UltraChart1.ChartType = ChartType.HistogramChart

        Me.UltraChart1.HistogramChart.ColumnAppearance.StringAxis = False
        Me.UltraChart1.HistogramChart.ColumnAppearance.ShowInLegend = True
        Me.UltraChart1.HistogramChart.LineAppearance.DrawStyle = LineDrawStyle.DashDot

        Me.UltraChart1.Axis.X.TickmarkStyle = AxisTickStyle.DataInterval
        Me.UltraChart1.Axis.Y.RangeMin = 0
        Me.UltraChart1.Axis.Y.RangeMax = 20
        Me.UltraChart1.Axis.Y.RangeType = AxisRangeType.Custom

        Me.UltraChart1.Axis.X.Labels.Orientation = TextOrientation.Horizontal

        Me.UltraChart1.Data.DataSource = getValues()
        Me.UltraChart1.Data.DataBind()

    End Sub
    Function getValues() As DataTable
        Dim dt As New DataTable
        dt.Columns.Add("Values", GetType(Double))
        dt.Rows.Add(New Object() {28.78})
        dt.Rows.Add(New Object() {28.78})
        dt.Rows.Add(New Object() {28.71})
        dt.Rows.Add(New Object() {28.97})
        dt.Rows.Add(New Object() {28.97})
        Return dt
    End Function
End Class
