Insert relative time scale in Visual C# 08

[pankil]

I am writing an application using Visual Studio 08 with measurement studio.

I want to use relative time scale on my X axis

I have tried using

graph.XAxes[0].MajorDivisions.LabelFormat = new NationalInstruments.UI.FormatString(NationalInstruments.UI.FormatStringMode.DateTime, "%<%H:%M:%S>t");

Doesnt work.

Can someone help me with this?

Hi Pankil,

It looks like you are close, but try using this formatting string "h:mm:ss tt":

graph.XAxes[0].MajorDivisions.LabelFormat = new NationalInstruments.UI.FormatString(NationalInstruments.UI.FormatStringMode.DateTime, "h:mm:ss tt");

 This line worked in an example program I modified, but let me know if you are still havingproblems in your code.

Hi Pankil,

It looks like the time stamps are showing up, the problem is just related to a scaling issue.  To fix this, make sure you are properly converting your time axis to the proper range using xAxis.Range.  If you are having trouble finding the correct values, please let me know how many data points you are plotting and what range you are using.

Hi,

I am using 5400 data points(90 min run)

I use (DateTime.Now - DateTimeStart).TotalSeconds for xaxis.

Hello Al B,

I did figure out solution for the issue

Using %H:mm:s or H:mm:s both work.

Could you elaborate what difference should '%' normally make?
