Re: [idvusers] How do you time step 3-hourly NARR data in the IDV?

Hi Mike...

The display rule is that if the data object has only one time, then it
is displayed along with all other "time steps"; hence, since both 18z
and 21z data have just one "time", they are displayed together.

I'm not familiar with the NARR data or how you are loading it, but
there are a couple of ways to make individual time period data be

1. using NCML to logically combine times
2. using the Chooser and picking more than one time/file using
SHIFT+click or CTRL+click
3. using the Formula under "Miscellaneous -> Make a time sequence from
single time grids"

Hope this helps.
