I would like to visualize my data in a scatterplot3d On my X and Y axis, I would like the same labels. Something like this: x<-c("A", "B", "c", "D") y<-c("A", "B", "c", "D") on the Z axis, I would like to show the comparison between labels in X and Y A with A A with B A with C A with D B with B B with C B with D C with C C with D D with D I have such a time series for this comparison. z<-c(0.25, 0.14, 0.15, 0.32, 0.79, 0.98,1.25, 0.68, 2.02, 0.64) How can I draw such a 3d scatter plot in r? thank you [[alternative HTML version deleted]]
