I have a file containing 2 columns like:
111, 3 122, 4 155, 3 192, 5 11, 9 123, 10 120, 23 How can I be able to write the data like ((111,122,155,192,11,123,120),(3,4,3,5,9,10,23)) . Now all I want to do is to plot it in a histogram using matplotlib.
please help with some basic ideas. !
Do you mean something like this?
>>> import numpy as np >>> import matplotlib.pyplot as plt >>> xs, ys = np.loadtxt('/tmp/example.txt', delimiter=',').T >>> print xs [ 111. 122. 155. 192. 11. 122. 120.] >>> print ys [ 3. 4. 3. 5. 9. 10. 23.] >>> plt.bar(xs, ys) <Container object of 7 artists> >>> plt.show()
