I run Ipthon in the terminal, in linux (not a jupyter notebook).
In Ipython 2.4.1, the following commands opens a pop up interactive Tk
plot window:
(prodEnv)[kv@loowkv1 sandbox]$ ipython IPython 2.4.1 -- An enhanced Interactive Python. ? -> Introduction and overview of IPython's features. %quickref -> Quick reference. help -> Python's own help system. object? -> Details about 'object', use 'object??' for extra details. In [1]: In [1]: %matplotlib Using matplotlib backend: TkAgg In [2]: import matplotlib.pyplot as plt In [3]: import numpy as np In [4]: plt.ion() In [5]: x = np.arange(0, 4*np.pi, 0.1) In [6]: y = [np.sin(i) for i in x] In [7]: plt.plot(x, y, 'g-', linewidth=1.5, markersize=4) Out[7]: [<matplotlib.lines.Line2D at 0x7f5c8a8b6410>]
In Ipython 5.0.0, when I use the same code:
(prodEnv)[kv@loowkv1 sandbox]$ ipython3 Python 3.4.1 (default, Nov 3 2014, 14:38:10) Type "copyright", "credits" or "license" for more information. IPython 5.0.0 -- An enhanced Interactive Python. ? -> Introduction and overview of IPython's features. %quickref -> Quick reference. help -> Python's own help system. object? -> Details about 'object', use 'object??' for extra details. In [1]: %matplotlib ...: import matplotlib.pyplot as plt ...: import numpy as np ...: plt.ion() ...: x = np.arange(0, 4*np.pi, 0.1) ...: y = [np.sin(i) for i in x] ...: plt.plot(x, y, 'g-', linewidth=1.5, markersize=4) ...: Using matplotlib backend: agg Out[1]: [<matplotlib.lines.Line2D at 0x7fe49ae9c208>]
nothing appears. How do I get my poping up interractive plot in Iptyhon 5.0.0?

Answer
From your output with ipython
using TkAgg
i.e. tk (python-tk) as backend.
Using matplotlib backend: TkAgg
But with ipython3
, it is agg
Using matplotlib backend: agg
I try with ipython3
and TkAgg
backend it’s working just fine as ipython
.
You may need to install python3-tk
to use TkAgg
with matplotlib
