Hi Inhyuk,

You have to turn off tick rounding:

dateTimeScale.RoundToTickMin = false;

This will make the axis start at first date time value. Another thing to consider is using one of the more advanced date time scales range / value timeline, which will annotate the axis better.

Hope this helps - let me know if you meet any problems.

Best regards,
Bob

 

hi~
I set date time format to AxisX, but it doesn't work.
Something wrong?

One more question.
I added DateTime data, it is started 01/03/2010.
But AxisX of chart is started earlier than 01/03/2010.
I want axis to start 01/03/2010.

thanks~~



Source code is here :

NChart m_Chart = this.xChart2.Charts[0];
NLineSeries line = (NLineSeries)m_Chart.Series.Add(SeriesType.Line);
line.UseXValues = true;
line.DataLabelStyle.Visible = false;
line.InflateMargins = true;

NDateTimeScaleConfigurator dateTimeScale = new NDateTimeScaleConfigurator();
dateTimeScale.LabelStyle.Angle = new NScaleLabelAngle(ScaleLabelAngleMode.Scale, 90);
dateTimeScale.LabelStyle.ContentAlignment = ContentAlignment.MiddleLeft;
dateTimeScale.AutoDateTimeUnits = new NDateTimeUnit[] { NDateTimeUnit.Day };
m_Chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator = dateTimeScale;

line.XValues.ValueFormatter = new NDateTimeValueFormatter("yy-MM-dd"); // It doesn't work

Random random = new Random();
DateTime startDate = new DateTime(2010, 03, 01);
DateTime endDate = startDate.AddYears(1);
TimeSpan span = endDate - startDate;
span = new TimeSpan(span.Ticks / 30);

if (span.Ticks > 0)
{
while (startDate < endDate)
{
line.XValues.Add(startDate);
startDate += span;

line.Values.Add(random.Next(100));
}
}
