resize ipython notebook output window

Question

You can toggle the scroll window in the main menu of the notebook

Cell -> Current Outputs -> Toggle Scrolling

Addendum #2: This comment: https://github.com/ipython/ipython/issues/2172#issuecomment-53708976 indicates how you can increase the maximum size of the output cells. Run the following code in the notebook:

%%javascript
IPython.OutputArea.auto_scroll_threshold = 9999;

I just placed my cursor in the grey box next to the output and clicked and then all of the output was displayed.

To resize the height of the scrollable output I do the following (you can change 44em):

from IPython.core.display import display, HTML
display(HTML("<style>div.output_scroll { height: 44em; }</style>"))

This worked for me in Chrome. Run it in a separate cell. Choose the max-height you want to display without scrolling.

%%html
<style>
.output_wrapper, .output {
    height:auto !important;
    max-height:1000px;  /* your desired max-height here */
}
.output_scroll {
    box-shadow:none !important;
    webkit-box-shadow:none !important;
}
</style>

You'll still get scroll bars if the contents exceed the max-height. There won't be a shadow box, though. Just increase the max-height even more if really don't want scrolling at all.

See the jupyter autoscroll extension (part of jupyter_contrib_nbextensions), which allows you to select when the output starts scrolling in a dropdown menu (you can set it to never scroll). The API used is not officially supported though, so this may break at any time.

For an plot.ly iplot I had to add the following to see any change (it changed all output)

%%html
<style>
.python-iframe > iframe {
  height:1000px !important;
}
</style>
