Graphics: working with ``go fland`''

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

[Output Graphic]

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_dset
      shade myvar
      go fland

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

      set data my_dset
      shade/x=lo:hi myvar
      go fland

Either set of commands above results in incorrect output.

Solution:

The solution is to be explicit in the longitude region.

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

    set data my_0_to_360_dset
    shade myvar
    go fland " " " " " " " " x=0:360

Using `set region':

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