[Matplotlib-users] [matplotlib-users] definition to show quikly a plot
Hello everyone, I have a problem. I have to look at many plots. Usely I do it like that: from pylab import* X1 = genfromtxt(Myfile.dat, usecols =(0)) Y1 = genfromtxt(Myfile.dat, usecols =(1)) plot(X1,Y1, label =My curve) show() But the problem is when I have many plots I have to copy paste and change manually all the name of the variables X1, X2, X3...etc. It's not really convenient. I want to create a def with the name of my file as argument which do something like that: from pylab import* def plotgraph(name): X_name = genfromtxt(name, usecols =(0)) Y_name = genfromtxt(name, usecols =(1)) plot(X_name,Y_name, label =name) plotgraph(MyFile) show() But it doesn't work. Do you know why? Do you have a smarter idea? Thanks!

I you pass name, the file name is name and not the what is in the variable. Just a note: if you read the file as 'X_name, Y_name = genfromtxt(name, usecols =(0,1)).T' you open, read and close the file only once. Cheers, Francesco But it doesn't work. Do you know why?

Thx Francesco, it works great!

2012/5/29 Fabien Lafont lafont.fab...@gmail.com: Thx Francesco, it works great! What for the .T at the end of genfromtxt? genfromtxt with usecols=(0,1) return an array with 2 columns. with .T you transpose it so that you can save it in two variables. For more info, e.g., http://docs.scipy.org/doc/numpy/reference/generated/numpy.ndarray.T.html#numpy-ndarray-t Cheers, Francesco 2012/5/29 Francesco Montesano franz.berges...@googlemail.com: Dear Fabien 2012/5/29 Fabien Lafont lafont.fab...@gmail.com: Hello everyone, I have a problem.
