Question:

How can I get `go fland' to fill the same region as the data?

Example:

yes? set data coads_climatology
yes? shade/x=-20:340 sst[l=1]
yes? go fland

Explanation:

The coverage issue arises because the ETOPO data sets are (presently) organized as 20E to 20E. If you do not explicitly set the longitude region, `go fland' will default to the ETOPO default region, not that of your data.

This typically happens in one of two ways:

• Using the dataset default region:

  set data my_0_to_360_dsetshade myvargo fland

• Setting the region as a qualifier (as in the example):

  set data my_dsetshade/x=lo:hi myvargo fland

Solution:

• Using `go fland' with an `x=lo:hi' argument:

  set data my_0_to_360_dsetshade myvargo fland " " " " " " " " x=0:360

• Using `set region':

  set data my_dset
  set region/x=lo:hi
  shade myvar
