the format of data expected by gnuplot depends on the type of plot:
regular plot: a number of values (each in a separate line)
multiCol plots: a number of lines, each containing a row
here, handle common situations;
however, if the data does not match, the program should have prepared the
data into a string and present it as such.
Strings will be sent as-is to the file
