How SPLASH plots the density projection of simulation data with only the 3D coordinates of the particles and no direct density given.

[Belloworldo]

I need better looking density projection maps with perspective effects for different angles, but I've been having trouble manipulating them:
I typed splash --hsoft=10 --normalize=off snapshot_000

Mass (by type) : 0.0000000000000000 1.0463387006893754E-003 2.3251971288118511E-004 0.0000000000000000 0.0000000000000000 0.0000000000000000 0.0000000000000000 0.0000000000000000
N_gas : 0
N_total : 60000
N data columns : 10
N data columns : 10
N data columns : 10 positions 60000
gas properties 0
ASSIGNING SMOOTHING LENGTH of h = 1.000E+01 to dark matter particles

last step ntot = 60000
warning: particle mass min = max = 0.00E+00
warning: u min = max = 0.00E+00
You may choose from a delectable sample of plots

---

1. x 6) v_z
2. y 7) particle mass
3. z 8) u
4. v_x 9) density
5. v_y 10) h

---

M) multiplot [ 4 ] m) set multiplot

d(ata) p(age) o(pts) l(imits) le(g) end h(elp)
r(ender) v(ector) x(sec/rotate) s(ave) q(uit)

Please enter your selection now (y axis or option) 2 ;
(x axis) (default=1). 1 ;
(render) (0=none) ([0:10], default=0). 9
The result is all red

Does it because particle mass is 0? Why does it still not work even though there are already Masses for type1 and 2 above
I would greatly appreciate it if anyone would like to help me!

this should work, can you post an example snapshot so I can have a look from my end? (maybe better on slack if it is a large file...)
