X axis range in Date-timestamp( X axis) Graph?

[eli_ela]

Hi all,
I’m plotting some data using Tgraph
In Xaxis the Date-Timestamp is given. I need to perform the analysis only in a limited range of the plot. How can I set the X axis range in this case?
An example of the data used are:
00:00:00 06/04/19 25.152
00:00:01 06/04/19 25.162
00:00:02 06/04/19 25.141
00:00:03 06/04/19 25.137
00:00:04 06/04/19 25.129
00:00:05 06/04/19 25.165

Thanks in advance
Eli

In reality, the x-axis keeps some “double” (“unsigned int”) values. See TAxis::SetTimeFormat and try e.g.:

TDatime(2019,12,1,16,32,54).Convert() // Sun Dec  1 16:32:54 UTC 2019
TDatime().Convert(kTRUE) // "now" in UTC

See also the TDatime and the TTimeStamp classes references and:

I’m plotting a certain quantity versus time. My dataset begins at 2012/03/14 00:00, and the UTC time stamp of the first event is 1331683214, which according to Python’s time library should be correct: >>> import time >>> time.gmtime(1331683214) time.struct_time(tm_year=2012, tm_mon=3, tm_mday=14, tm_hour=0, tm_min=0, tm_sec=14, tm_wday=2, tm_yday=74, tm_isdst=0) However on the X axis of my plot the data starts from 2012/03/14 01:00 when configuring the time axis with: axis->SetTimeFormat("#spl…
