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