Background

There are many datasets in the world that are formed in such a format below:

var1	var2     ...	varM	res1	res2 	...	resN
----------------------------------------------------------
v(1,1)	v(1,2)	 ...	v(1,M)	r(1,1)	r(1,2)	...	r(1,N)
v(2,1)	v(2,2)	 ...	v(2,M)	r(2,1)	r(2,2)	...	r(2,N)
...
v(K,1)	v(K,2)	 ... 	v(K,M)	r(K,1)	r(K,2) 	...	r(K,N)

Which is a K(M+N)* matrix. Each line means one "experiment result" (possibly). This is more like a multi-input, multi-output blackbox, while the variables settled down, we can know the results:

var1...M |----------| res1...N ---------> | The BOX | --------> |----------|

Sometimes, we want to know how the variables influnce the results. But... The data is too huge, and I don't want to sort it, select data, draw graph each time to see the curves. So...

I decided to write this tool to draw all the curves for me.

Input of this drawer should be *.csv file currently.

Required software

Currently this tool only works under Linux.

Required binaries

  • gnuplot
  • convert
  • eog

Required Perl modules

  • Chart::Gnuplot
  • Term::Menus

Usage

Please check --help.

CSV file format

Please take sas-15k-data.csv as am example. It's format Should be something like:

var1,var2,var3,...,varM,,res1,res2,...,resN
var1,var2,var3,...,varM,,res1,res2,...,resN
var1,var2,var3,...,varM,,res1,res2,...,resN

Here to seperate variables from test results, I used two commas ,, to seperate (or to say, add an empty column beteween the two blocks if you open it in an Excel application).
