> 2. create a LabPlot project, add new notebook in it
> 3. import numpy, matplotlib : is ok

This 'inline' command is from ipython. In Cantor you don't need to use it, we
rely on python only. With the option "Plot Integration" you can control where
the produce plot result is opened in the external viewer used by matplotlib,
etc. or embedded into Cantor's notebook. The following example should work:
import matplotlib.pyplot as plt
import numpy as np
t = np.arange(0,2*np.pi, 0.1)
x = 16*np.sin(t)**3
y = 13*np.cos(t)-5*np.cos(2*t)-2*np.cos(3*t)-np.cos(4*t)
plt.plot(x,y)
plt.show()
I just tried it and saw the produce plot is not properly embedded if the plot
integration option is activated :-( But this must be a different problem.
Please give it a try without any ipython specific keywords.
