I have data that depicts a 3D distribution of points caracterizing a star. So in short words, I have a random 3D distribution of points inside a sphere. I want to do a 3D plot of all the points except all of them that are within the x>=0,y>=0,z>=0 sector. That is I want to cut out 1/8 of the sphere. My attempt:
spl 'data' u ($2>=0.?($3>=0.?($4>=0.?1/0:$2):$2):$2):3:4:7 w d lc palette z
does nothing. I mean, it seems to plot everything. Columns are $2=x, $3=y, $4=z and $7 a magnitude to give the color to the points.
Any idea of what I'm doing wrong?
Thanks!
lc palette cb
instead oflc palette z
