I have been looking around for packages that will do this but I am not stumbling on the right one. I would like to make a 3d plot (hopefully an interactive graphic (rgl maybe)) that is simply four 2d graphs stacked next to each other traveling down river. site is the x-axis, bas is the y-axis, and month is the z axis. I would be open to any other suggestions on how to visualize this date station month bas 190 5 0.000 190 7 1.563 190 10 0.000 190 11 0.000 202 4 18.750 202 5 18.750 202 7 6.250 202 10 4.800 202 11 3.125 198 4 18.750 198 5 31.250 198 7 3.125 198 10 3.200 198 11 12.500 205 4 0.000 205 5 0.000 205 7 0.000 205 10 0.000 205 11 0.000 thanks Stephen -- Let's not spend our time and resources thinking about things that are so little or so large that all they really do for us is puff us up and make us feel like gods.
