 I am just writing the function for this but I've got a problem with the 
 quotation marks.
 This:
 printf "set timefmt \"%Y%m\" \n"
 results in
 <output>
    *** error in function plot_ts_y2axis, line 42
    > printf "set timefmt \"%Y%m\" \n"
 </output> 
printf takes '%' as starting a conversion specifier. If you want a 
literal '%' in the output, as you do here, you need to double it:
printf "set timefmt \"%%Y%%m\"\n"
