| # This script is an almost total rewrite by Louwrentius |
| # of the original fio_generate_plots script provided as part of the FIO storage |
| # benchmark utiliy. I only retained how GNUplot is used to generate graphs, as |
| # that is something I know nothing about. |
| # |
| # The script uses the files generated by FIO to create nice graphs in the |
| # SVG format. This output format is supported by most modern browsers and |
| # allows resolution independant graphs to be generated. |
| # |
| # This script supports GNUPLOT 4.4 and higher. |
