[Cdat-discussion] Basic questions on vcs

[Dave H. <dav...@me...>]

Hello,
I am a CDAT/VCS newbie, hoping to be pointed in the right direction.

My ultimate goal is to write a script that displays plots from our (UKMO)
portable climate model interactively -- i.e. showing plots from specified
variables for the previous model days.

I have had success with selecting parts of the data (latitude, longitude,
and time values) and have been able to plot from example files.

I have several tasks yet to be completed that I feel stuck on.  I have
read through the .pdf's and the tutorials but I am not still not able to
figure out exactly what to do.

These tasks are:

1.  Flipping the plot.  Because the Met Office uses north-to-south in
the model I am using, the plots I am able to do are all upside down.  I am
wondering whether there is a way to flip the plot in vcs, or whether I am
going to have reorder the data in the files somehow.

2. Multiple plots on one canvas.  This is mentioned in the vcs tutorial
but I can't get my head around it.  My goal is to have 12 plots -- 3 rows
(representing 3 days) and 4 columns (representing six hour intervals
during a day).  Is this a matter of creating a new template with these
specifications?

3. Overplotting.  For each of the 12 plots, I want to plot a boxfill
(representing precip) and plot an isoline (representing pressure) over the
top of it.  Again, is it a matter of fiddling with templates?


I appreciate any help.

Thanks
