[GRASS-dev] v.krige and variogram preview

[Anne Ghisla]

Hi devs,

the split of v.krige into script and GUI broke the variogram preview -
programmatically it was based on global variables, that worked when
the code was all in one script.
The point is that variogram preview needs to load data before hitting
"Run" button. AFAIK, GRASS modules usually collect parameters and then
run the appropriate command. I thought about creating a new module,
v.krige.variogram, and call it from v.krige GUI only to draw the
variogram and give the parameters back to v.krige. It could also be
run separately.
What do you think? Thanks in advance for suggestions.

regards
Anne
