Thanks Graham, Actually using local Jupyter instance I can open the saved jypyter notebooks and all Brunel charts persists and can open without rerun. I have problem only on Bluemix Jupyter notebook instance where I can't persist the Brunel charts. Whenever I open the saved jupyter notebook I need to rerun the notebook in order to display the Brunel charts. I don't think it's useful to save as pure image. Just how it works in local jupyter I expect to work on Bluemix. In both cases I use "%AddJar -magic http://www.brunelvis.org/jar/spark-kernel-brunel-all-1.0.jar
" to import the Brunel library into notebook.
