My data is on an irregular grid. Is there a sequence of modules I could use to reduce? What about show positions? I tried running import through show positions, then specifying every tenth one, but I got an error. > >2) I would like to use the compute module (or any module which works) to > >take the length of each vector in the field and output a scalar field. > > Run your data through Compute and use the expression: mag(a) > > > > >3) If (2) can be accomplished, I would like to make the autoglyphs plot > >vectors based on magnitude. > > Not quite sure what you mean here.

Once I have the magnitude of each vector, I would like to plot the vector field using only those vectors from my field which have a certain magnitude or greater. The scalar is still associated with the position point of the vector, correct? kate white [EMAIL PROTECTED] > > >
