My google search and search in PyCharm plugins list results as little helpful
So I raise it here, how to remove SciView pane in PyCharm?
Under Settings => Tools => Python Scientific
Uncheck the (only) box "Show plots in toolwindow"
. Future plots should appear "normally" and not in SciView.
To remove from the side panel entirely, right click on the SciView tab, and select "Remove from Sidebar".
