Well, thanks for taking time off to help and the link! Two things, if
I may.

#1. The above code needs a minor modification to plot correctly, since
n_elements(time) = 10, I would need to add:

<code>

plot,time2,field,xticks=9,XTICKN=strtrim(fix(time),2)+'hrs'

</code>

to plot correctly.

#2. My time arrays are rather large. I actually did a reverse when I
ran into this problem, as in setting:

<code>

time_array[where(time_array ge 24.)]=time_array[where(time_array ge
24.)]-24.

</code>

Anyway, I should admit that it was clever of you to think of changing
the ticknames, reminds me that I should RTFM more.. I haven't thought
of that at all. Since the whole point was to make it more "human
readable" as in resetting time to be 000hrs at midnight and then
increase, I guess for plot purposes, your method would suffice!
Because all I need is to display as above, nothing changes, except the
format of the time displayed :-)

Thanks,
