Hi, I was wondering if there is a way to control the size of the plot being shown on the terminal, since it always takes the whole terminal window no matter the figsize

Since I'm using conda I don't have a set PYTHONPATH, can you help me out? I tried using conda develop and pointing to the repo, but despite it being added to the path.
Output of python -c "import sys; print(sys.path)"

['', '/home/joaogui/miniconda3/lib/python37.zip', '/home/joaogui/miniconda3/lib/python3.7', '/home/joaogui/miniconda3/lib/python3.7/lib-dynload', '/home/joaogui/miniconda3/lib/python3.7/site-packages', '/home/joaogui/Downloads/matplotlib-backend-kitty']

Background

Due to complex nature of my Python projects that are often deployed in the cloud and involve external non-Python dependencies I usually prefer to isolate my environments using Docker rather than through Python's native mechanism of virtual environments.

Issue

The backend doesn't really work inside a Docker container. I tried to add kitty as a dependency (which I'd try to avoid regardless) but it didn't really help.

Solution

Use kitty's native protocol instead of kitty +kitten icat to make it work both inside and outside Docker containers.

Hello. I'm having an issue where Matplotlib's facecolor options for the outside background is not working :

Situation 1 - should show white background if facecolor is not specified:

Situation 2 - should show the color specified on facecolor, but shows grey:

Situation 3 - Works normally without using MPL/Kitty backend:

I found on the code a reference to this:

Removing the , facecolor='#888888' option makes it work just like normal matplotlib does:
No facecolor setting shows as white:

Specified color shows correctly:

I'm creating a PR for this change (see below).

I am using Kitty 0.24.4 under MacOS 12.3 with Python 3.8.13 installed with Conda and Matplotlib 3.5.1

Would be nice to be able to pip install this.

Firstly, thanks for the module, it has been hugely helpful for me on daily basis!

Secondly, calling plt.show() with matplotlib==3.6.0 (specifically matplotlib-3.6.2-cp310-cp310-manylinux_2_17_x86_64.manylinux2014_x86_64.whl) release results in

UserWarning: Matplotlib is currently using module://matplotlib-backend-kitty, which is a non-GUI backend, so cannot show the figure.
  _Backend.show(*args, **kwargs)

(same goes for matplotlib-backend-notcurses, btw).

I am, unfortunately, at a loss, if I am simply missing something. Please let me know if I can help with more information.

I'm using python 3.11.1 with ipython 8.8.0 and got this error on trying to plot:

[ins] In [6]: plt.show()
/home/fbence/Codes/matplotlib-backend-kitty/__init__.py:83: UserWarning: Matplotlib is currently using module://matplotlib-backend-kitty, which is a non-GUI backend, so cannot show the figure.
  _Backend.show(*args, **kwargs)

Background

When playing around with Python, especially when plotting graphs is involved, I use ipython most of the time.

Issue

The backend doesn't recognise ipython as an interactive environment.

Solution

Pick a different heuristic that recognises ipython, python -i and simple python in an interactive shell as interactive.

I cloned the repository to my current directory, opened python, ran the following -

import matplotlib
matplotlib.use('module://matplotlib-backend-kitty')
import matplotlib.pyplot as plt
import pandas; pandas.Series(range(10)).plot()

It shows only a grey picture. Solid grey.
then I tried

plt.show()

Nothing.
