Use browser debugging tools (e.g. F12 or Ctrl+Shift+J in Chrome) to
view - access to the Vega View object. See Vega Debugging Guide
on how to inspect data and signals at runtime. For Vega-Lite,
VEGA_DEBUG.view.data('source_0') gets the main data set.
For Vega, it uses the data name as defined in your Vega spec.
vega_spec - Vega JSON graph specification after some modifications by Kibana. In case
of Vega-Lite, this is the output of the Vega-Lite compiler.
vegalite_spec - If this is a Vega-Lite graph, JSON specification of the graph before
If you are using Elasticsearch query, make sure your resulting data is
what you expected. The easiest way to view it is by using "networking"
tab in the browser debugging tools (e.g. F12). Modify the graph slightly
so that it makes a search request, and view the response from the
server. Another approach is to use
Dev Tools tab - place the index name into the first line:
GET <INDEX_NAME>/_search, and add your query as the following lines
(just the value of the
If you need to share your graph with someone, you may want to copy the
raw data response to gist.github.com, possibly
.json extension, use the
[raw] button, and use that url
directly in your graph.
To restrict Vega from using non-ES data sources, add
to your kibana.yml file.
