I found this useful (at least as a stopgap measure while waiting for Trac#21267 <https://trac.sagemath.org/ticket/21267>, which may be not as easy as it seems...), and thought that documenting this might be useful to people wanting interactive displays in Sagemath Jupyter notebooks :
The ipywidgets <https://github.com/ipython/ipywidgets> python package can be installed in the Sage jupyter notebook. To enable installation "in the right place", the installation instructions <http://ipywidgets.readthedocs.io/en/latest/user_install.html#with-pip> should be modified as : sage -pip install ipywidgets echo "jupyter nbextension enable --py --sys-prefix widgetsnbextension" | sage -sh if you use the Sage Jupyter notebook (the original installation instructions are enough if you have installed your Sage kernel in the system's Jupyter notebook). The following code snippet is enough to use the package : from __future__ import print_functionfrom ipywidgets import interact, interactive, fixedimport ipywidgets as widgets And that's all... My limited testing seems to validate this (ab?)use of the package : var("x,a,b") dbeta(x,a,b)=x^(a-1)*(1-x)^(b-1)/beta(a,b) def showbeta(a,b): show(plot(dbeta(x,a,b),(x,0,1),figsize=4)) return(None) interact(showbeta, a=widgets.FloatSlider(min=0.0,max=10.0,step=0.1,value=1.0,continuous_update=False), b=widgets.FloatSlider(min=0.0,max=10.0,step=0.1,value=1.0,continuous_update=False)); Note that the ipywidget package has no way to use a lot of Sage data types. Any argument to them have to be cast to native python data types (int, float, string). Clunky, but damn useful, at least for pedagogic purposes...
