My solution produces a chart with the x-axis being in 24-hour time. That is I have 21:00 22:00 et cetera this works well on my development machine. When I publish to the Web server the times changed to am/pm so that is 9:00 pm 10:00 pm and so on. I surmise the chart is reading it from the computer it is running on. I doubt I can change that so how do I force the NEVRON chart to write 24-hour time? It is ASP.NET using a web form.
I have tried using
dateTimeScale.LabelValueFormatter = new NDateTimeValueFormatter("HH:mm");
but it makes no difference.

Hi Mike,

You're correct - the control uses the current machine (server) culture settings for label formatting. To override this behavior you can use:

NDateTimeScaleConfigurator dateTimeScale = new NDateTimeScaleConfigurator();
dateTimeScale.EnableUnitSensitiveFormatting = false;

NDateTimeValueFormatter labelFormatter = new NDateTimeValueFormatter("HH:mm");
labelFormatter.CultureInfo = CultureInfo.InvariantCulture;
dateTimeScale.LabelValueFormatter = labelFormatter;

This will ensure that you always use the same culture settings regardless of the server.
We hope this helps - let us know if you meet any problems or have any questions.
