Disable iPython Notebook Autoscrolling
PythonPython 2.7IpythonJupyter NotebookPython Problem Overview
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.
Python Solutions
Solution 1 - Python
Can also be done via user interface.
- Individual cells: Cell->Current Outputs->Toggle Scrolling
- All cells: Cell->All Outputs->Toggle Scrolling
Solution 2 - Python
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.
Solution 3 - Python
To prevent scrolling within a single cell output, select the cell and press Shift+O while in command state. It will toggle output for that particular cell. If you want all the cells to display long outputs without scrolling, then go to the Cell tab -> All Outputs -> Toggle Scrolling. That's it !!!
Solution 4 - Python
This works for me (with no semicolon)
%%javascript
IPython.OutputArea.auto_scroll_threshold = 9999
Solution 5 - Python
To disable scroll to bottom after run all command, execute this code:
%%javascript
require("notebook/js/notebook").Notebook.prototype.scroll_to_bottom = function () {}
Solution 6 - Python
In the similar way that you can [hack a cell to autorun][1], you can add the following cell:
%%javascript
require(
["notebook/js/outputarea"],
function (oa) {
oa.OutputArea.auto_scroll_threshold = -1;
console.log("Setting auto_scroll_threshold to -1");
});
which will set the auto_scroll_threshold to -1 which means never autoscroll.
This works on my notebooks that are trusted (e.g. jupyter trust notebook.ipynb), not sure if any cells are executed in untrusted notebooks.
