     % xyplot --dataset-file  input1.txt  --dataset-file  input2.txt \
              --dataset-color red         --dataset-color blue \
              --dataset-style linespoints --dataset-style points

    Arguments ('*' denotes required arguments):

    *   chart_title => *str*

    *   dataset_files => *array[filename]*
