|
|
|
|
# To use this script you'll need to install R: http://www.r-project.org/
|
|
|
|
|
# and a library for R called ggplot2
|
|
|
|
|
# Which can be done by starting R and typing install.packages("ggplot2")
|
|
|
|
|
# like this:
|
|
|
|
|
#
|
|
|
|
|
# shell% R
|
|
|
|
|
# R version 2.11.0 beta (2010-04-12 r51689)
|
|
|
|
|
# > install.packages("ggplot2")
|
|
|
|
|
# (follow prompt)
|
|
|
|
|
#
|
|
|
|
|
# Then you can try this script by providing a full path to .data file
|
|
|
|
|
# outputed from 'make bench'
|
|
|
|
|
#
|
|
|
|
|
# > cd ~/src/node
|
|
|
|
|
# > make bench
|
|
|
|
|
# ...
|
|
|
|
|
# > ./benchmark/plot.R .benchmark_reports/ab-hello-world-buffer-1024/ff456b38862de3fd0118c6ac6b3f46edb1fbb87f/20101013162056.data
|
|
|
|
|
#
|
|
|
|
|
# This will generate a PNG file which you can view
|
|
|
|
|
#
|
|
|
|
|
#
|
|
|
|
|
# Hopefully these steps will be automated in the future.
