Disable iPython Notebook Autoscrolling

Question

In iPython Notebook, is it possible to disable the autoscrolling of long outputs? Or at least set a threshold for the output length before autoscrolling sets in?

Tried the following command

%%javascript IPython.OutputArea.auto_scroll_threshold = 9999; 

but it gives an error

Javascript error adding output! SyntaxError: Unexpected identifier See your browser Javascript console for more details. 

Answer 1

Can also be done via user interface.

• Individual cells: Cell->Current Outputs->Toggle Scrolling
• All cells: Cell->All Outputs->Toggle Scrolling

Answer 2

To disable auto-scrolling, execute this javascript in a notebook cell before other cells are executed:

%%javascript IPython.OutputArea.prototype._should_scroll = function(lines) {     return false; } 

There is also an ipython notebook extension, disable_autoscroll, you can use for a more permanent change. Follow ipython issue #2172 for the latest details.
