pandas - python plot frequency with continuous integer labeled x-axis -


i'm trying make frequency plot special x-axis request based on following pandas table.

     pos               freq 0     67                  1 1    285                  5 2    288                  1 3    397                  4 4    592                  1 5    640                  3 

since frequency integers (pos column), hope have x-axis normal continuous numeric labels. however, simple bar plot:

plot_pos=pos_freq.plot(kind='bar',x='pos') 

i x-axis labeled 67, 285, 288, 397, 592, 640. instead, x-axis series of continuous integers/intervals, e.g. 60, 65, 70, 75, ....645, 650; , frequency bars still shown @ correct positions.

i'm not sure if bar plot choice @ point, , i'm new plotting in python. (i in excel; or can add x-axis...) suggestion better method appreciated!

with matplotlib,

import matplotlib.pyplot plt plt.bar(pos_freq['pos'], pos_freq['freq']) plt.show()
