Hi martin,

your first problem seems to be to make a plot with given units. Here is

a simple example: we wannt to plot Sin[x] where the x axis has units of

Pi and the y axis units of 1/10:

Plot[10 Sin[Pi x],{x,0,2}]

Plot[10 Sin[Pi x],{x,0,2},AxesLabel-> {StyleForm["Units of

Pi",FontSlant->Italic],StyleForm["Units of 1/10",FontSlant->Italic]}]

hope this helps, Daniel
