Hello,

This is little frustrating since it should work fine.

I'm trying to plot distribution of stars with sphere shape points using
idlgrsymbol
THe followings are what I used.

Here array is the 3D (3 column and 3000 rows) array of stars.

x1 = array[0,*]
x1 = reform(x1) ;make as 1D array

y1 = array[1,*]
y1 = reform(y1)

z1 = array[2,*]
z1 = reform(z1)

orb1 = obj_new('orb', color = [0,0,255], radius = 0.2)
orb1 -> scale, 1,1,1
sym1 = obj_new('idlgrsymbol', orb1)

xplot3d, x1, y1, z1, symbol = sym1, linestyle =6

I used "scale" to be 1, 1, 1 in x, y, and z axis such that it makes a
sphere.
BUt, somehow, in my final plot, the plotted points look like an
ellipsoid ellongated in z axis.

Am I missing something here???
