Out of the box solutions for python/pyplot:
import matplotlib.pyplot as plt
plt.plotfile('yourfile.csv', cols=(0, 1, 2), delimiter=',',
subplots=False, names=['$x$', '$Label1$', '$label2$'])
plt.grid(True)
plt.show()
and Gnuplot:
set grid ytics
plot 'yourfile.csv' using 1:2 with lines, 'yourfile.csv' using 1:3 with
lines
The viewers are a bit clunky but they do let you zoom and pan.

Pete
