If you just have a couple of them, one quick and dirty trick is to select the plot on one figure, copy it from the menu or ctrl-c, then select the axis on the other figure and paste it.
So there isnt a way in general to draw a 5d or 6d shape in any language - once you are past 3d it is hard, and actually since our screens are 2d, even that loses information. Normally you can add axis by adding time (to get a 4d diagram) and color (to add a 5th dimension), and perhaps if it is a scatter plot you could do size of symbols to represent a 6th dimension, but in practice doing 2d slices is the best way in my experience. Ie, Do multiple 2d graphs instead of 1 5d graph.
