Jupyter notebook

For use in a Jupyter notebook use the %matplotlib notebook backend. As of now you cannot rerun the cell which is showing the plot without restarting the notebook, otherwise the plot will disappear.

See examples/simple.ipynb

TODOs

• document how to extend
• better support for jupyter notebook
• user definable layout (mutiple columns)
• add new plot types
• persistent storage/loading of log
