I was wondering if its possible to use Numeral.js in custom vega graphs to format results into human readable values, and if so, how to do it. In my use case I want to format bytes to a number with the best prefix as per Numeral Formatting | Kibana Guide [master] | Elastic
I can see there a format function which is used in the sankey example, and also mentioned in this forum post but as far as I can tell this the d3js format function and not the Numeral.js format.
Hi, this is a good question. Unfortunately you can't mix these two things- the Vega formatting is totally separate from Kibana formatting. We actually have a way that we could mix the two, but it's never come up before.
