Bar Width in chart with few datapoints

[User (Legacy)]

I have a bound horizontal bar chart on a page.  Usually this chart shows 

eight values, but sometimes there are only a few data points (like at 

the end of the datatable).  when that happens the bars get very wide.

Is there any way to force the chart to draw the bars exactly the same 

width even if there is only one or two data points?

The same as what ? The same as when there is <n> datapoints ? If this is 

what you want simply increase the number of points to <n> and fill their 

values with Chart.Hidden.

Thanks.

I had actually just started down that route, but I am having trouble 

understanding how to add the points.  I know that the size of the 

DataTable is usually 10 records because we are doing paging using stored 

procedures.

The following is the skeleton of my FillChart Procedure.  I have used 

OpenData() in an old VB 6 app where the date is in arrays, but how do I 

add or insert the points when I am binding to the DataTable.

After binding occurs, you can use OpenData and fill the rest of the points. 

For example:

private void CompleteWithHidden (int newPointCount)

{

    int oldPointCount = chart1.NValues;

    chart1.OpenData(COD.Values,chart1.NSeries,newPointCount);

    for (int i = 0; i < chart1.NSeries; i++) {

        for (int j = oldPointCount; j < newPointCount; j++) {

            chart1.Value[i,j] = Chart.Hidden;

        }

    }

    chart1.CloseData(COD.Values);

}
