unpacking multiple files

Community matplotlib-users

Friends,

  1. I want to make a plot of multiple lines. I want to make something like

./multiplot.py 1.dat 2.dat 3.dat … n.dat

All files contain two columns and are of same length. plotfile() and load() do not take list of file but one file name only. In such cases, I want to unpack the x,y values in 1.dat,2.dat… n.dat and plot it at a stretch. What is the best way to do it. Any suggestion would be highly helpful.

  1. How can i fix the default values, like first line should be black, second line in red …, third in blue.

Thanks

Hi Bala,

you may just run through the list sys.argv like

for filename in sys.argv:
    plotlfile(filename, ...)

2) How can i fix the default values, like first line should be black,
second line in red ...., third in blue.

define your own favourite color-list like

my_colors = ['black', 'red', 'blue']

and afterwards circle through this like:

for index, filename in enumerate(sys.argv):
    plotlfile(filename, ..., color=my_colors[index])
