Perhaps 'plot' is not the ideal interface for your purposes. How about something like this: #!/usr/bin/env python import matplotlib from matplotlib.lines import Line2D import pylab import numpy as npy def myplot(ax, matrix, linestyle, color): for column in range(1, matrix.shape[1]): line = Line2D(matrix[:,0], matrix[:,column], linestyle=linestyle, color=color) ax.add_line(line) colors = 'brk' for d in range(2,5): fig=pylab.figure() ax=fig.add_subplot(111) matrix = npy.random.rand(d,d) matrix[:,0] = npy.linspace(0, 1, num=d) myplot(ax, matrix, '-', colors[d-2]) pylab.show() -- Jouni K.

Handling the sys.argv was not the problem; actually my main problem is to tell the 'plot' or 'loglog' command, that I have a different number of arrays. Lets say I have to columns, the I could use in a script: res=plot(array_mapped[:,0],array_mapped[:,1], 'b', array_mapped[:,0],array_mapped[:,2], 'g') The next time a have 5 columns in a file and want to plot all 5 columns without adjusting the 'plot' command in the script, but just by defining an argument when starting the script. I have to adjust somehow dynamically the plot command to adjust the number of graphs in one figure; but that is the problem...

Does nobody have an idea; especially for the 'dynamic' number of plotted arrays!? Regards!

[Matplotlib-users] plot different columns
Hi, I have a small script which reads a csv file with several columns and puts it into an scipay array, which I can plot using matplotlib. It works fine, but just with explicitly setting the number of columns: res=loglog(array_mapped[:,0],array_mapped[:,1], 'b', array_mapped[:,0],array_mapped[:,2], 'g', array_mapped[:,0],array_mapped[:,3], 'r', array_mapped[:,0],array_mapped[:,4], 'y', array_mapped[:,0],array_mapped[:,5], 'k', array_mapped[:,0],array_mapped[:,6], '-bo', linewidth = 2) Is there a way to define the number of columns, which I want to plot? Or even better, can I apply an sys.argv to define the plotted columns, e.g. "python csvplot.py all": which plots all columns with its value for the y-coordinate and the line-number as x-coordinate "python csvplot.py all1": which does the same as above, but using column 1 as abscissae "python csvplot.py 1 2 5": which plots columns 2 and 5 against column 1... Would be nice, if anybody has an idea, how to achieve this!? Regards! Fabian - This SF.net email is sponsored by: Microsoft Defy all challenges.
