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.
Knowing what the error was would help you troubleshoot this.
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?
So what you want to do is with your field a, a = Replace(a, a, "data", "vectors") #This copies orig. vec. to new component a = Compute(a, "mag(a)") a = Include(a, "min val", ...) a = Replace(a, a, "vectors", "data") #Now put vectors back. a = AutoGlyph(a) Image(a) David
