I'm using Spyder 3.5 and trying to change the number of IPython Console buffer line. The default is 500 lines. But no matter what number I change to, the limit is still 500, and I cannot scroll back beyond 500 lines. I also open a new console after changing the preference but it still doesn't work. Any idea why?
Change your settings in the IPython console rubric (Tools->Preferences->IPython console). Also make sure to reload spyder or open a new Ipython console for the changes to take effect.
