Hi Ethan,

your suggested code works great for single plots, thank you very much for that. But now I am struggling to do the same for each plot in a multiplot.I know that the code used to generate multiplots no longer take effect once you change the margins, I haven't been able to get it just right. 

Any suggestions? 

thanks in advance.
Dom
