Hi, I came accross this example of visualising a 3D histogram of a data sets:
data1 = RandomVariate[NormalDistribution[0, 1], {100, 2}];
data2 = RandomVariate[NormalDistribution[1, 1], {100, 2}];
Manipulate[SmoothHistogram3D[{data1, data2}, ColorFunction -> Function[{x, y, z}, Hue[z]]]]
I am wondering, what are the two components {100, 2} in the two data sets referring to?
