## automated iteration over multiple columns

If you want to create a histogram from many columns of data in a single file, it is very convenient to use the plot iteration feature. See plot for. For example, to create stacked histograms of the data in columns 3 through 8

          set style histogram columnstacked
          plot for [i=3:8] "datafile" using i title columnhead
