I have generated a Table in 3 dimensions, for two variables x, y.

grid = {{{1, 1}, {0, 1}, {0, 2}, {0, 3}, {0, 4}, {0, 5}}, {{1, 0}, {1, 
   1}, {1, 2}, {1, 3}, {1, 4}, {1, 5}}, {{2, 0}, {2, 1}, {2, 2}, {2, 
   3}, {2, 4}, {2, 5}}, {{3, 0}, {3, 1}, {3, 2}, {3, 3}, {3, 4}, {3, 
   5}}, {{4, 0}, {4, 1}, {4, 2}, {4, 3}, {4, 4}, {4, 5}}}

and I have computed values for each point using Map[myFunction[#[[1]], #[[2]]] &, grid, {2}], which has given me

myOutput = {{-3.8627*10^-23, 0.000246833, 3.08541*10^-8, 2.57117*10^-12, 
  1.60698*10^-16, 8.03492*10^-21}, {0., -3.8627*10^-23, 0., 0., 0., 
  0.}, {0., 0., 0., 0., 0., 0.}, {-1.8303*10^-26, 0., 0., 0., 0., 
  0.}, {0., 0., 0., 0., 0., 0.}}

I have the grid in Dimensions {5,6,2} and my values in Dimensions {5,6}. I would like to have a plain but readable table that has one one axis one dimension of the grid, on the other the other dimension, and the table cells containing the function values. Basically a ListPlot3d, but not as a plot, but with numbers. How can I achieve that?

  • $\begingroup$ Isn't MatrixPlot[ ] or ArrayPlot[ ] what you're after? $\endgroup$ Sep 25, 2015 at 15:02
  • $\begingroup$ Or even Grid[ ] $\endgroup$ Sep 25, 2015 at 15:03
  • $\begingroup$ @belisarius MatrixPlot and Grid both are almost there, but I can't find a way to add the grid (the coordinates from grid) to the picture. $\endgroup$

  • $\begingroup$ Well you don't really have a grid: some coordinates are missing (e.g., (0,0)), and others are duplicated. (e.g., (1,1)). $\endgroup$

  • $\begingroup$ @Alan my calculations are not valid on the (0,0) point, so that was my quick-and-dirty solution to that. If this is an issue, feel free to replace the first (1,1) with (0,0) again. $\endgroup$

$\begingroup$
grid = Flatten[grid, 1]
myOutput = Flatten[myOutput, 1]
stubs = Sort@DeleteDuplicates[Map[First, grid]]
headers = Sort@DeleteDuplicates[Map[#[[2]] &, grid]]
MapThread[Rule, {grid, myOutput}]
Table[{i, j}, {i, stubs}, {j, headers}] /. % /. {_, _} -> Null
TableForm[%, TableHeadings -> {stubs, headers}]

enter image description here

TableForm[myOutput, TableHeadings -> {Range[0, i - 1], Range[0, j - 1]}]
