Embed options are lost #7

Hugovdberg · 2021-05-31T08:42:33Z

I include several altair plots in a Sphinx project, and I wish to set the locale to Dutch. In Jupyter I can use the following to set the locale:

import altair as alt
from vega_datasets import data
import requests

resp = requests.get('https://raw.githubusercontent.com/d3/d3-format/master/locale/nl-NL.json')
nl_format = resp.json()
resp = requests.get('https://raw.githubusercontent.com/d3/d3-time-format/master/locale/nl-NL.json')
nl_time_format = resp.json()
alt.renderers.set_embed_options(formatLocale=nl_format, timeFormatLocale=nl_time_format)

source = data.stocks()
plot = alt.Chart(source).mark_line().encode(
    x='date',
    y='price',
    color='symbol',
).interactive()
plot

However, when exporting to json/html or using sphinxext these settings are lost from the embed options:

print(plot.to_html())

      vegaEmbed("#vis", spec, embedOpt)
        .catch(error => showError(el, error));
    })(vegaEmbed);

  </script>
</body>

The variable embedOpt is missing the configured locale settings.

I can workaround this in the sphinx extension by rewriting the jinja2 template for the plot, at least hard coding the required options, but I would expect these settings to be included automatically.

import altair.sphinxext.altairplot as altsphplt
import jinja2
altsphplt.VGL_TEMPLATE = jinja2.Template(

Please follow these steps to make it more efficient to solve your issue:

Since Altair is a Python wrapper around the Vega-Lite visualization grammar, most bugs should be reported directly to Vega-Lite. You can click the Action Button of your Altair chart and "Open in Vega Editor" to create a reproducible Vega-Lite example and see if you get the same error in the Vega Editor.
Search for duplicate issues.
Use the latest version of Altair.
Describe how to reproduce the bug and include the full code and data to reproduce it, ideally using a sample data set from vega_datasets.

Thanks - sphinx does not use the renderers framework, unfortunately, so renderer settings will not apply. You'll need to find another way to specify those settings. Renderers are what are used to render charts in Jupyter/IPython environments.

jakevdp · 2021-05-31T16:25:05Z

I think this is more of a documentation issue than a bug, to be honest.

Hugovdberg · 2021-05-31T17:33:08Z

Through some digging in the code I see that it is possible to call plot.to_html(embed_options=alt.renderers.options['embed_options']), which includes the options in the embedOptions for saving, but that option appears to be missing from the sphinxext altogether. I would expect those options to be included automatically, or at least to provide a shorthand. So this is indeed more of a documentation issue.

Regarding sphinx, perhaps the renderers framework is not the most appropriate location for the embed options in sphinx, but those settings are still relevant in the sphinx context I think. Perhaps the sphinx extension could pick up the locale settings from sphinx and apply those to the plots, or allow specification of the embed options in conf.py?

I saw this message in the CI of Altair in the build run that might be related to this issue:

@mattijn that warning ended up being unrelated to this

fix: Avoid sphinx error "Code Execution failed:NameError: name 'format_locale' is not defined" altair#3503

Obviously you'd know this now, just adding here to rule things out
