Neptune-Altair Integration

This integration lets you log interactive charts generated in altair, like confusion matrix or distribution, in Neptune.

Follow these steps:

0. Create an experiment:

   import neptune
   
   neptune.init(api_token='ANONYMOUS',project_qualified_name='shared/showroom')
   neptune.create_experiment()
   

1. Create and log altair charts into Neptune:

   import altair as alt
   from vega_datasets import data
   
   source = data.cars()
   
   brush = alt.selection(type='interval')
   
   points = alt.Chart(source).mark_point().encode(
       x='Horsepower:Q',
       y='Miles_per_Gallon:Q',
       color=alt.condition(brush, 'Origin:N', alt.value('lightgray'))
   ).add_selection(
       brush
   )
   
   bars = alt.Chart(source).mark_bar().encode(
       y='Origin:N',
       color='Origin:N',
       x='count(Origin):Q'
   ).transform_filter(
       brush
   )
   
   chart = points & bars
   

   from neptunecontrib.api import log_chart
   
   log_chart(name='altair_chart', chart=chart)
