Hi, thanks in advance for looking into this :)

In my datatable which is the source of my chart, I have few columns that are not included, then I have a datetime column called "Date" then I have one column "Energy" whose data i want to show in the Y_axis  representing the energy value of each datetime value of my "Date" column.

How do I tell the charting system what the date column name is so the system puts the right datetimes in my X_Axis.

Because for now, the system puts some dates in my x_axis that are not included in my "Date" column values of my datatable . My date column values go from april 2011 to end april 2011, but i get the x_axix ranging from october 2011 till end october 2011.

My  linechart is defined in markup with axis x like this:

<

X Visible="True" TickmarkInterval="0" Extent="61" LineThickness="1" TickmarkStyle

="Smart">

<MajorGridLines Visible="True" DrawStyle="Dot" Color="Gainsboro" Thickness="1" AlphaLevel

="255">

</MajorGridLines

>

<MinorGridLines Visible="False" DrawStyle="Dot" Color="LightGray" Thickness="1" AlphaLevel

="255">

</MinorGridLines

>

<Labels ItemFormatString="&lt;ITEM_LABEL&gt;" HorizontalAlign="Near" VerticalAlign

="Center"

Orientation="VerticalLeftFacing" Font="Verdana, 7pt" FontColor

="DimGray">

<SeriesLabels HorizontalAlign="Near" VerticalAlign="Center" Orientation

="VerticalLeftFacing"

Font="Verdana, 7pt" FontColor="DimGray" FormatString

="">

<Layout Behavior

="Auto">

</Layout

>

</SeriesLabels

>

<Layout Behavior

="Auto">

</Layout

....

>

</Labels

>

and in my code behind i have this:

where constants.usercolname represents the energy column:

protected

e)

{

try

target = 0.0;

;

;　　

)axisY.Map(target);

)axisX.MapMinimum;

)axisX.MapMaximum;

(xEnd, targetYCoord));

targetLine.PE.Stroke =

.Gray;

targetLine.PE.StrokeWidth = 1;

e.SceneGraph.Add(targetLine);

}

ex)

{

, ex.StackTrace);

}

}

private void ConfigureChart(ref Infragistics.WebUI.UltraWebChart.UltraChart chart, DataTable dt, bool besoinReelGraph)

{

"<DATETIME_VALUE>";

chart.Axis.X.RangeMin = Provider.StartDateDefault.Date.AddMinutes(1).Ticks;

chart.Axis.X.RangeMax = Provider.EndDateDefault.Ticks;

Hashtable t = new Hashtable();

chart.LabelHash = t;

LineAppearance App1 = new LineAppearance();

chart.LineChart.LineAppearances.Add(App1);

false;

chart.Data.IncludeColumn(

"id", false);

chart.Data.IncludeColumn(

"Date", false);

chart.Data.IncludeColumn(

Constants.BESOINREELCOLNAME, false);

Constants.MINPREVCOLNAME, false);

chart.Data.IncludeColumn(

Constants.HOURPREVCOLNAME, false);

chart.Data.IncludeColumn(

Constants.USEDCOLNAME, true);

chart.Data.IncludeColumn(

"FRCTTIME", false);

// columns labels

new string[] { "Besoin prévue" });

// colors

new Color[] { Color.Blue };

chart.LineChart.LineAppearances[0].LineStyle.DrawStyle = Infragistics.UltraChart.Shared.Styles.

LineDrawStyle.Solid;

chart.LineChart.LineAppearances[0].Thickness = 1;
