PLOTCOLS plots data in columns of a matrix. One x column and any number of y columns can be chosen. Also the mean of the columns can be subtracted and the columns can be divided by their standard deviation. Another option is to divide by the maximum absolute value.
This is very useful for comparing differently scaled data taken over time in one plot without the need to type long commands!
Also, you can specify a name for each column, which is used for the legend and the x-axis label, and a LineSpec as in the plot function.

Added 'max' option to the input corr. 'max' will divide each column by its maximum absoute value before plotting. It can be catenated with the other options 'sd' and 'mean'.
