Hi!

First of all im sorry i flipped the axis. i have my dates on the x and the decimals on the y axis.

But now i will explain the problem further. I have a datatable with two columns. The first one is a datetime and the second one a decimal. If i have values in the decimal column all works perfect. But sometimes it can happen that all values in the second column are "0". If that's the case i get the OverflowException.

Here the Stacktrace:

   at System.Drawing.Graphics.DrawLine(Pen pen, Int32 x1, Int32 y1, Int32 x2, Int32 y2)

It's a strange error. Maybe you can help.

I was still unable to reproduce the problem. This actually might be something that was fixed in the past, so try the following code snippet and if it breaks, try downloading and installing the latest service release for your version of NetAdvantage.

DataTable dt = new DataTable();
dt.Columns.Add("col1", typeof(DateTime));
dt.Columns.Add("col2", typeof(decimal));
dt.Rows.Add(new object[] { DateTime.Parse("1/1/2010"), 0 });
dt.Rows.Add(new object[] { DateTime.Parse("2/1/2010"), 0 });
dt.Rows.Add(new object[] { DateTime.Parse("3/1/2010"), 0 });
dt.Rows.Add(new object[] { DateTime.Parse("4/1/2010"), 0 });
dt.Rows.Add(new object[] { DateTime.Parse("5/1/2010"), 0 });

ultraChart1.ChartType = ChartType.LineChart;

ultraChart1.LineChart.TreatDateTimeAsString = false;
ultraChart1.Data.SwapRowsAndColumns = true;
ultraChart1.DataSource = dt; 

Thanks for your help, but I am getting the error again. But thats not such a tragedy because we will switch to a hight version i a few months.

But if someone might have an answer it would be great. We use Infragistics 2003 (V3) at the moment.

Again thankt for your help.

In a case where you have all 0s, you can try setting a manual range on your Y axis. Something like this:

if (all zeroes)
  chart.Axis.Y.RangeMin  = -1
  chart.Axis.Y.RangeMax = 1
  chart.Axis.Y.RangeType = AxisRangeType.Custom

Thank you for this answer!

It works perfectly for me.

Again, thank you very much!
