I have a data set gathered from lab. measurements of the form {x,y,z}. I want to plot this data in a way that there is (1) no interpolation between adjacent data points and (2) that is visualised in the form of cubes i.e. {x,y} give the location of the cuboid whilst z gives the height and then repeat this simply for all data points.

I have tried ListContourPlot and ListDensityPlot with InterpolationOrder -> 0, howvere I ged wierd results. For example, both plots don't show the squares or rectangular patches that I was expecting, instead they seem more triangular.

I have attached an image of a couple of my plots:

.

And this is the code that I have used to generate these plots:

GraphicsGrid[{{ListContourPlot[scanDataCh1, Mesh -> None, 
InterpolationOrder -> 0, PlotRange -> All, 
ColorFunction -> "Rainbow", 
FrameLabel -> {"Hem. Voltage (V)", 
  "Elevation Angle \!\(\*SuperscriptBox[\((\), \(o\)]\))", 
  "ListContourPlot for Channel 1"}, ImageSize -> Large], 
ListDensityPlot[scanDataCh1, Mesh -> None, InterpolationOrder -> 0,
 PlotRange -> All, ColorFunction -> "Rainbow", 
FrameLabel -> {"Hem. Voltage (V)", 
  "Elevation Angle \!\(\*SuperscriptBox[\((\), \(o\)]\))", 
  "ListDensityPlot for Channel 1"}, ImageSize -> Large]}}]

Thanks!
