# [✓] Why ListPlot3D does not show the z values?

GROUPS:
 I wanted to display something simple with ListPlot3D. I started out with these values: a = b = c = 0.01; cnt = 2; xmin = -3*a; xmax = 8.9*a; dx = N[Pi/300/cnt^2]; ymin = -2*b; ymax = 2*b; dy = N[Pi/300/cnt^2]; zmin = -6*c; zmax = 4*c; dz = N[Pi/300/cnt^2]; Then I created this list: lrbmfdxcor = Flatten[ParallelTable[{x, y, z}, {x, xmin, xmax, dx}, {y, ymin, ymax, dy}, {z, zmin, zmax, dz}], 2]; It looks like this: Then I tried to display it with ListPlot3D. I got this, /seeing on edge/: What am I not doing right?Thanks ahead, János

 Because for some x,y points you have multiple values… For example your first two data points are both for -0.03, -0.02. I'm not sure what you want to visualize, but you might need ListContourPlot3D or a dimensions reduction.

 Yes, I know. These are some Mesh Points and I just wanted to see them without the value assigned to them. The Documentation does not say that all {xi,yi,} values must be different, so I assumed ListPlot3D has the built in intelligence to display minimum one zi value for the many same xi,yi points.
