Hi all, I want to plot in a 3D cartesian graph a list of (x,y,z) points, in order to visualize clusters of data. Apparently, 3D graph in HiQ can plot just z data orginized in array, meaning that you have to assign z values for all the combinantions of x and y. For example, how can I plot (1,1,1) and (3,3,3) as two single points of the 3D space? Thank you for your help. Roberto.
