Hello,

I'm looking for an example for using a given DateTime on the PrimaryX Axis.
How can i set a DateTime-Format for the X-Axis for example "YYYY. MM. DD. HH. MM " /"2011. 08. 01. 10.05" ?

Best Regards,

Alexander

Hi Alexander,

You'll have to change the date / time value axis formatter:

 

using Nevron.Dom;
using Nevron.Chart.WinForm;
using Nevron.Chart;
using Nevron.GraphicsCore;

NChart chart = nChartControl1.Charts[0];
NLineSeries line = new NLineSeries();
line.Values.Add(10);
line.Values.Add(20);
line.Values.Add(30);

DateTime now = DateTime.Now;
line.XValues.Add(now.ToOADate());
now += new TimeSpan(200, 0, 0, 0);
line.XValues.Add(now.ToOADate());
now += new TimeSpan(200, 0, 0, 0);
line.XValues.Add(now.ToOADate());

line.UseXValues = true;
chart.Series.Add(line);

NDateTimeScaleConfigurator dtScale = new NDateTimeScaleConfigurator();
dtScale.EnableUnitSensitiveFormatting = false;
dtScale.LabelValueFormatter = new NDateTimeValueFormatter("yyyy MM dd HH MM");
chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator = dtScale;

nChartControl1.Refresh();

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

When I try this example the dates start with 1899.

What am I doing wrong?

Hi Daniel,

Most likely you did not specify that the series uses X values:

someSeries.UseXValues = true;

In that case the control generates automatic x values starting from 0 which maps to date time representation of 1899.

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