A collection of small scripts for quickly plotting and munging data from the
command line. Supports basic statistics, histograms, CDFs, and more. An
importable python module is also available: see python/
for more.
Compute summary statistics:
$ cat data.txt | mean
$ cat data.txt | stdv
$ cat data.txt | summary
Plot data generated from script:
$ python gen_xy.py | plot
Bin data and then plot:
$ cat ages.txt | count | plot # frequency counts
$ cat xy.data.txt | aver | plot -c "set title 'xy'" -p "with points" # trendline of xy-data
Compute cumulative distribution of data and plot:
$ cat samples.txt | ccdf > samples_ccdf.txt
$ cat distrib.dat | ccdfplot
$ cat data.txt | awk '$1>0 {print $1}' | ccdfplot --log --funcs 'x**-1'
Fit a (nonlinear) function to data:
$ cat current_voltage.dat | curvefit "a0*exp(a1*x)"
$ cat xy.dat | curvefit "A*sin(x/B)+C" B=3 --noplot --verbose # start parameter B at 3
$ cat tutorial/x.dat | bin | curvefit "A*exp(-x**2/B)" # fit histogram
All functions have help strings (use -h
or --help
):
$ mplot -h
$ el2info --help
See tutorial/
for more information.
Get the git repository:
$ cd
$ git clone git://github.com/bagrow/datatools.git
Then add the datatools/bin
directory to your path. For example, put
if [ -d "$HOME/datatools/bin" ]; then
export PATH=~/datatools/bin:$PATH
fi
in your bashrc
.
- bash and awk (very common)
- gnuplot (and X11 terminal)
- python 2.x (probably 2.5+) with packages:
- numpy (version with fixed histogram normalization, around 1.6+)
- scipy (only for
ksdensity
,normaltest
,ranksum
,kstest2
,rs_ks_tests
andpvalue_nonzero_slope
) - networkx (only for
el2info
,el2gcc
, andel2draw
) - matplotlib (only for
el2draw
)
- R and the robustbase package (only for
linear_model
)
Recent versions of, e.g., OS X include everything but gnuplot, networkx,
matplotlib, and R. Some knowledge of gnuplot is very helpful for customizing
plot appearance as the -p
and -c
options use valid gnuplot code.
If you need to install some of these dependencies on OS X, I strongly encourage you to check out Homebrew.
