| 4 | # of the original fio_generate_plots script provided as part of the FIO storage |
| 5 | # benchmark utiliy. I only retained how GNUplot is used to generate graphs, as |
| 6 | # that is something I know nothing about. |
| 7 | # |
| 8 | # The script uses the files generated by FIO to create nice graphs in the |
| 9 | # SVG format. This output format is supported by most modern browsers and |
| 10 | # allows resolution independent graphs to be generated. |

| 12 | # This script supports GNUPLOT 4.4 and higher. |
