Hi Matheus,
The 'view' function at present directly returns the matplotlib plot objects. When developing with the Jupyter notebook, the resulting figure is indeed persistent. In other environments, it may indeed be transient. This sounds like your experience.
It was designed this way so users can directly access the figure and customize it further if desired.
I should mention that when looking into this, I found that one of the view methods only returned the figure object, not both figure and axis. This is now fixed. So if you are about to write some code, I'll push a minor point release shortly which includes this fix which has more consistent behavior looking forward.
Regards,
Josh
