Hello Maki,
you might like to have a look in our local IDL guide
as I came across this problem in the summer. There are two routines
in the guide that might help you. vector.pro plots a regular grid of
vectors and is a master calling routine to plot_vector.pro which plots
an individual vector. It's at
http://ncas-cms.nerc.ac.uk/index.php?option=com_content& task=view&id=94&Itemid=122

The example code and data is a link on the right hand side.

Cheers
Andy
