Hello guys, I was able to plot when I only had 1 column. But now I have a CSV file that has 10,000 rows and 12 columns. I am trying to write a code to plot all these 12 columns into 12 subplots of one graph. Below found is my code for just one column in one csv file. BTW csv2rec does not work in my version of matplotlib.
import matplotlib.pyplot as plt import pylab datafile1 = 'ch1_s1_lrr.csv' datafile2 = 'ch1_s1_baf.csv' a1 = pylab.loadtxt(datafile1, comments='#', delimiter=';') b1 = pylab.loadtxt(datafile2, comments='#', delimiter=';') v1 = [0,98760,0,1] v2 = [0,98760,-2,2] plt.figure(1) plt.subplot(2,1,1) print 'loading', datafile1 plt.axis(v2) plt.plot(a1, 'r.') plt.subplot(2,1,2) print 'loading', datafile2 plt.axis(v1) plt.plot(b1, 'b.') plt.show() Now I want to be able to import 12 columns from the same file and plot all the values of the 1st six columns and only the values less then 0.05 for the next six columns. I am a beginner for python and matplotlib and I have never used arrays before so I am stuck at this point for a more than a week. Please help!!! Any help is appreciated. Thank you for your time and valuable suggestion Karthik
