In another thread I said, > Imo, Leo should aim to provide all the rendering capabilities of the IPython Qt shell and the Jupyter notebooks.
In some sense, Leo's --ipython command-line operation already gives Leo these capabilities. When I enter (in IPython's Qt console) the example in the qtconsole docs <http://jupyter.org/qtconsole/stable/#inline-graphics>, I see pretty much what is shown, except that the graphics appear as a separate pane on both Ubuntu and Windows 10. The big question is, *how much extra work will it take to make this work in Leo itself ?* Hmm. Let's put the code in the body pane... The following works, but the print gets swallowed by the IPython console: from scipy.special import jn print(jn) *Note*: I am using the Anaconda distribution. g.es(jn) shows: <ufunc 'jv'> which presumably is some kind of IPython/scipy magic. Going on, this throws a NameError. linespace is not defined: x = linspace(0,4*pi) Oh good, the exception (stderr) *does* show up in the console. Presumably, IPython defines linespace somehow. Googling `scipy linspace` yields entries for `numpy linspace'. This works: from scipy.special import jn from numpy import linspace, pi x = linspace(0,4*pi) g.es(x) x is array of numbers, just like what is shown in the IPython Qt console for x. Doh, querying `linespace` in the Qt console shows: <function numpy.core.function_base.linspace> This is better than googling :-) Querying `plot` in the Qt console shows: <function matplotlib.pyplot.plot> Drum roll please, what happens when we execute?: from scipy.special import jn from matplotlib.pyplot import plot from numpy import linspace, pi x = linspace(0,4*pi) for i in range(6): plot(x, jn(i,x)) Hurray! This puts up a matplotlib plot, identical to the plot created from the IPython Qt console! *Summary* Leo can *already* do everything (in Leo's body pane) that IPython can do in the IPython Qt console. A few extra imports are needed, but that's so easy to do in Leo! Write the import once and forget about it. This is an important realization for me.
