From c2d10a4cbd48f60f70c56466f70867f867fb41ed Mon Sep 17 00:00:00 2001 From: Amit Shah Date: Wed, 15 Apr 2009 19:15:17 +0530 Subject: Add gnuplot script that draws bar graphs for results The results from running the test via the run_tests.sh script are not yet formatted the way this gnuplot script needs them to be, but when formatted so, this script can be used to draw the bar graphs. My knowledge on gnuplot is elementary; just about 1h worth of searching and reading the demo files and this is a modified script I picked up from the gnuplot website. More customisations are surely possible, like piping the resulting image to image processors and dumping a png directly instead of 'copy to clipboard'->paste in gimp->save. The run_results.txt file that this script parses should look like this: filesystem posix-fallocate mmap chunk-4096 chunk-8192 posix-fallocate mmap chunk-4096 chunk-8192 ext2 74 96 761 81 33 37 37 36 ext3-writeback 87 97 202 93 34 40 39 36 The first set of 4 columns contains seconds; the 2nd set contains fragments.
