Please test the following with both Python 2 and Python 3.

  • Basic plotting with the default backend using the pylab module:
# basic plotting with default backend
from pylab import plot, show

plot([1,2,3])
show()

  • Basic plotting with the default backend using the maplotlib package:
# basic plotting using the matplotlib interface
import matplotlib.pyplot as plt

plt.plot([1,2,3])
plt.show()

The default backend is Qt4Agg. The next scripts will test theeTkAgg backend.

  • Basic plotting with the TkAgg backend using the pylab module:
# basic plotting with default backend
import matplotlib
matplotlib.use('TkAgg')

from pylab import plot, show

plot([1,2,3])
show()


  • Basic plotting with the TkAgg backend using the maplotlib package:
# basic plotting using the matplotlib interface
import matplotlib
matplotlib.use('tkagg')

import matplotlib.pyplot as plt
plt.plot([1,2,3])
plt.show()
