My primary use case is to be able to render interactive charts with multiple renderers (alt.renderers.enable("altair_saver", fmts=["html", "svg"]) without getting warnings about the window coming back and getting rendered into a notebook or other nbconvert export.

Closes #51. @jakevdp Would love your review and happy to tweak as needed – this was my quick and dirty approach to pass the arguments through, but if there's a more elegant way of doing so, please let me know!

Hello,

I am trying to generate an SVG figure, but I got an error. Could you please guide me how to fix this? Thank you

This runs fine whenever I run the script as a user. I have added export DISPLAY=:0; before my script as noted here to no avail. I am calling altair_saver like so:

world_file    = f'{PWD}/data/world_covid.vg.json'
save(world, world_file)

I attempted installing the nodeJS packages which resulted in a malformed chart.

Sorry if its a stupid issue, but I cant import the package after installing. It asks me for a modole that should be installed with the conda instalation.

Hi, I am saving svg's using altair_saver in my code, and up until a few minutes ago, everything was fine. But now I am getting the following error message:

No enabled saver found that supports format='svg'.

Is there anything broken?

Hello, I'm using altair 4.0.1 and produce a chart using alt.themes.enable('fivethirtyeight')

When I use chart.save('foo.html') it uses the colors and layout from the theme that looks something like this (cropped oddly due to data sensitivity)

But when I use chart.save('foo.png') or chart.save('foo.svg'), the colors and layout are from the default theme

I tried looking in the docs for changing the theme on a chart and for save and couldn't find how to specify the theme when saving pngs and svgs.

Thank you for the development of this!

I have this sample code:

import pandas as pd
import altair as alt
from altair_saver import save

df = pd.read_csv("tmp.csv",keep_default_na=False)

df['year'] = pd.to_datetime(df['year'], format='%Y')

chart=alt.Chart(df).mark_area().encode(
    alt.X('year:T', timeUnit = 'year',title='year',axis=alt.Axis(tickCount='year')),
    alt.Y('v:Q',axis=alt.Axis(format='%'),title='percentage'),
    color='i:N'
)

save(chart, "chart.png")

If I run it, I have

This seems to have been caused by a missing setup for the chromedriver.

It worked once I had installed and set up everything, validating by using an example that should open a Browser:

from selenium import webdriver
browser = webdriver.Chrome()
browser.get('https://jupyter.org/')

For me the steps were:

• conda install -c conda-forge python-chromedriver-binary
• And grabbing the latest stable https://sites.google.com/a/chromium.org/chromedriver/home
  • I assume that the python-chromedriver-binary should include it but it did not fix the issue and this is Windows and Conda so 🤷...

Now it works.

Posting here so future MEs will find it via Google.

I'm wondering what the best way is to setup altair to always render pngs.

I'm working in jupyter-lab.

I want my notebooks to be readable on github by default.

At the moment, I'm using this little show method:

import tempfile
from IPython.display import Image

def show(chart):
    file = tempfile.mktemp(suffix='.png')
    chart.save(file)
    return Image(file)

Hello,

I am having an issue with saving altair charts after doing an install with conda on a miniconda3 docker image. The versions I am using are: altair 4.1.0 and altair_saver 0.5.0

This error is thrown when the chart is saved: Fontconfig error: Cannot load default config file

The resulting png when using the Window Rank Example then contains square symbols instead of the expected characters.

I expect this is due to the fonts in this docker image being installed different than other systems, but other packages seem to be able to handle this and find the fonts which are indeed available in the underlying Debian Image.

This issue is not present when saving to html, but with png, svg and pdf.

Saving a chart as .png causes an "CalledProcessError" error when using method "node" and npm version is node@9

Reason is that npm has removed command: "npm bin" since version 9 which is used in _node.py (npm_bin)

Chinese fonts are displayed normally in HTML format. Garbled characters when exporting to PNG format.

`import pandas as pd import altair as alt from altair_saver import save

df = pd.DataFrame({"x":[0.5,1,2], "y" : [0.5,1,2], "text": ["你好", "中国", "明天"]})

pic = alt.Chart(df).mark_text().encode( x = "x", y= 'y', text ='text' ) save(pic, "text.png")`

Is there anyway to set the webdriver parameter one time so that all save("chart.png") calls behave like save("chart.png", webdriver="firefox")?

I couldn't find this parameter documented on the site or the repo.

Further, my geckodriver log mentions "Missing chrome" which may be related:
