Help support me

While I love my job as a researcher, it doesn't exactly bring home the bacon. I mean.. it brings home some bacon... but like... not enough bacon? Right. Anyway, a colleague suggested I add an optional donation badge so users can help support projects like jupyter-themes (and the forthcoming lab-themes which will give users similar control over the look and feel of Jupyter Lab. Currently in early stages of development).

I firmly believe that software is best served open and, as such, am committed to providing free and easy access to all my code. So if you can't make a financial contribution, then don't and pip install it anyway! But if you're sitting on some extra cash and enjoy using a package I've developed, then any amount helps and I greatly appreciate it.

JT Customizable Features

plotting style




pandas dataframes


command palette




  • Python 2.7, 3.4, 3.5, 3.6
  • Jupyter (Anaconda recommended)
  • matplotlib

Install with pip

# install jupyterthemes
pip install jupyterthemes

# upgrade to latest version
pip install --upgrade jupyterthemes

Known issues

  • for best results: use notebook>=5.6.0 (pip install --upgrade notebook)
  • refreshing / removing / resetting: depending on your system, browser, etc., you may need to empty your browser cache after installing a new theme (-t) or attempting to restore the default (-r) in order for those changes to take effect. (see discussion here). At the very least you'll need to refresh your browser window (usually cmd+r or ctrl+r).
  • install issue: if you get an error saying jt is not recognized, try this fix.
  • slow render when scrolling: fix available here

Command Line Examples

# list available themes
# onedork | grade3 | oceans16 | chesterish | monokai | solarizedl | solarizedd
jt -l

# select theme...
jt -t chesterish

# restore default theme
# NOTE: Need to delete browser cache after running jt -r
# If this doesn't work, try starting a new notebook session.
jt -r

# toggle toolbar ON and notebook name ON
jt -t grade3 -T -N

# toggle kernel logo.  kernel logo is in same container as name
# toggled with -N.  That means that making the kernel logo visible is
# pointless without also making the name visible
jt -t grade3 -N -kl

# set code font to 'Roboto Mono' 12pt
# (see monospace font table below)
jt -t onedork -f roboto -fs 12

# set code font to Fira Mono, 11.5pt
# 3digit font-sizes get converted into float (115-->11.5)
# 2digit font-sizes > 25 get converted into float (85-->8.5)
jt -t solarizedd -f fira -fs 115

# set font/font-size of markdown (text cells) and notebook (interface)
# see sans-serif & serif font tables below
jt -t oceans16 -tf merriserif -tfs 10 -nf ptsans -nfs 13

# adjust cell width (% screen width) and line height
jt -t chesterish -cellw 90% -lineh 170

# or set the cell width in pixels by leaving off the '%' sign
jt -t solarizedl -cellw 860

# fix the container-margins on the intro page (defaults to 'auto')
jt -t monokai -m 200

# adjust cursor width (in px) and make cursor red
# options: b (blue), o (orange), r (red), p (purple), g (green), x (font color)
jt -t oceans16 -cursc r -cursw 5

# choose alternate prompt layout (narrower/no numbers)
jt -t grade3 -altp

Set Plotting Style (from within notebook)

jtplot.style() makes changes to matplotlib's rcParams dictionary so that figure aesthetics match those of a chosen jupyterthemes style. In addition to setting the color scheme, jtplot.style() allows you to control various figure properties (spines, grid, font scale, etc.) as well as the plotting "context" (borrowed from seaborn).

Note, these commands do not need to be re-run every time you generate a new plot, just once at the beginning of your notebook or whenever style changes are desired after that.

Pro-tip: Include the following two lines in ~/.ipython/profile_default/startup/startup.ipy file to set plotting style automatically whenever you start a notebook:

# import jtplot submodule from jupyterthemes
from jupyterthemes import jtplot

# currently installed theme will be used to
# set plot style if no arguments provided

jtplot.style() Examples

# import jtplot module in notebook
from jupyterthemes import jtplot

# choose which theme to inherit plotting style from
# onedork | grade3 | oceans16 | chesterish | monokai | solarizedl | solarizedd

# set "context" (paper, notebook, talk, poster)
# scale font-size of ticklabels, legend, etc.
# remove spines from x and y axes and make grid dashed
jtplot.style(context='talk', fscale=1.4, spines=False, gridlines='--')

# turn on X- and Y-axis tick marks (default=False)
# turn off the axis grid lines (default=True)
# and set the default figure size
jtplot.style(ticks=True, grid=False, figsize=(6, 4.5))

# reset default matplotlib rcParams
