Hi-
I'm trying to do something which intuitively ought to be quite simple:
I have a data file which looks like:
x_pos,y_pos,v_radial
The data is of ~ 450 ejecta knots in a supernova remnant (3c58 for the
curious). I basically want to make a 'kaboom' type 3-d distribution
with the coords x,y,v_rad, since v_rad is effectively a measure of the
z displacement from the center. The positions should be marked by an
arrow which points radially away from (0,0,0), has a length
proportional to the data, and optionally a color based on the value
(bluer for positive, redder for negative values). Is this an easy thing
to do? So far, all I've been able to do is:
ImportSpreadSheet->(Mark x 3, for each value)->Compute (to make a
vector)->Unmark->Autoglyph->Image
but this only makes a distribution of circles, which looks nice, but
isn't quite what I have in mind.
Any suggestions?
Thanks,
Dan
