different increment displayed on the x (time) axis then the one grads picks? I normally<br>
use 'set xlint', but that didn't work for real dates (like in the exmaple below). A look in<br>
the grads documentation confirmed that 'set xlint' does not work for a date/time axis.<br>
Does anyone know what to do instead?<br>

You could also try using the "skip" command. Perhaps something like this<br>
will also work for you:<br>
<br>
set time 00z01jun2007 00z01jul2007<br>
set missconn on (if connecting lines desired, as Mike suggested)<br>
d skip(air,4)<br>
<br>
Above should display data only at 00z timesteps (assuming 4x daily as in<br>
your sample).<br>

Re: skipping time<br>
<br>
<br>
<br>
<br>
<br>
<br>
I came up with a way to do this. It is not elegant, but works, and I would<br>
be happy to see another option. The idea is to maskout all other times<br>
except the one you want to plot. However, grads won't let you take a<br>
single time variable, and expand that into a time series so that it can<br>
mask the other times. So, here goes, for 00Z:<br>
<br>
set time 18Z1Jul2004 00Z2Jul2004<br>
define m1=1<br>
set time 00Z2Jul2004 06Z2Jul2004<br>
define m2=1<br>
set time 00Z2Jul2004 18Z2jul2004<br>
define m3=m2*m1 *m3=1 at 00Z2Jul, undef all others<br>
modify m3 diurnal * now m3=1 for all 00Z<br>
<br>
set time 00Z1Jul2004 18Z31jul2004<br>
display var*m3<br>
<br>
The display should have a time series of 00Z points. If you want those<br>
points connected then prior to display, set missconn on.<br>
<br>
Hope it helps,<br>
<br>

Dear GrADS-users,<br>
<br>
I have a very simple question which is probably easy to answer as well.<br>
<br>
I have temperature data in a timeseries of, let's say, 120 timesteps (30<br>
days times 4 points per day; 00z 06z 12z and 18z). Using GrADS I want to<br>
display a selection of this data, namely only temperature at 00Z and<br>
skipping the other timesteps, thus display times 1, 4, 9, and so on. Is<br>
there a simple statement to do this in GrADS or do I need to end up<br>
writing a script for this?<br>
<br>
Kind regards,<br>
Herbert ter Maat<br>
