Grouping X axis with time

[#1]

Hi,

I am working on a bar chart with x axis has the date& time in 1/02/2012 12:30:00 AM.

Now i needed to group this x axis with time value for example

grp1 12:00:00 AM to 6:00:00 AM

grp2 6:00:00 AM to 12:00:00 PM

And can please advice the function to read only the time from this1/02/2012 12:30:00 AM

thanks all

If you have to get the hour, the function is "Hour()",  of course... (is not a joke)

Get a look also to "Class()" function; it may help you
