Chart Control and Dates give strange results

[Eric Duesing]

If I take a chart control and drop it on the form then add the following to form load:

ChartSeries s= chartControl1.Model.NewSeries("Licenses",ChartSeriesType.Area);
s.Points.Add(Convert.ToDateTime("4/4/2004 12:00:00"),81);
s.Points.Add(Convert.ToDateTime("4/11/2004 12:00:00"),84);
s.Points.Add(Convert.ToDateTime("4/18/2004 12:00:00"),82);
s.Points.Add(Convert.ToDateTime("4/25/2004 12:00:00"),87);
s.Points.Add(Convert.ToDateTime("5/2/2004 12:00:00"),94);
s.Points.Add(Convert.ToDateTime("5/9/2004 12:00:00"),104);
s.Points.Add(Convert.ToDateTime("5/16/2004 12:00:00"),112);
s.Points.Add(Convert.ToDateTime("5/23/2004 12:00:00"),112);
s.Points.Add(Convert.ToDateTime("6/1/2004 12:00:00"),116);
s.Points.Add(Convert.ToDateTime("6/6/2004 12:00:00"),116);
s.Points.Add(Convert.ToDateTime("6/13/2004 12:00:00"),127);
chartControl1.Series.Add(s);
chartControl1.Legend.Visible=false;
chartControl1.PrimaryXAxis.ValueType=ChartValueType.DateTime;

I would expect it to give me the dates along the bottom, no? I''m using 2.0.5.1.

Thanks for asking this Eric, as I''m having the dilemna with 2.0.6.0.

I do this:

ChartSeries cs = this.m_ChartControl.Model.NewSeries(string.Format("{0} Product Projection", nYear), ChartSeriesType.Bar);
cs.Points.Add(new DateTime(nYear, 1, 1), Convert.ToDouble(drv["productproj"]));
cs.Text = cs.Name;
cs.Type = ChartSeriesType.Column;

I''ve got these settings for the x axis:

PrimaryXAxis.ValueType = ChartValueType.DateTime;
PrimaryXAxis.IntervalType = ChartDateTimeIntervalType.Years;
PrimaryXAxis.DateTimeFormat = "yyyy";

And I get 1899 for each column.

What''s up with that?

Hi,

Please add this line to set the Indexed mode to false and the values will be interpreted properly:

this.chartControl1.Indexed = false;

It would also help to rotate the labels along the X axis to prevent them from overlapping:

this.chartControl1.PrimaryXAxis.LabelRotate = true;

this.chartControl1.PrimaryXAxis.LabelRotateAngle = 90;

Thank you for your patience.

Regards,

Davis

Doh! You are correct.
