Hi! I'm trying to display an stacked bar with information in a double nested array in Vega. I know that people struggle with this and I've read other questions/responses, but I still cannot get this right. This is the response that I have from ES. I need to display the frequencies, and for each fr…

@nyuriks / @flash1293 can we please get some help? Thanks, Bhavya

With format: { property: aggregations.freqs.freq.buckets }, I suppose you may need flatten transform for rangos.buckets field to flatten the nested buckets. To debug vega scripts, "Inspect" page will help you. You can see the intermediate results [image]

Hi! I'm trying the flatten transform, but still get undefined for the rangos.buckets.doc_count :frowning: I'm trying this: transform: [ { flatten: [ rangos.buckets ] } { calculate: datum.key as: frequencies } { calculate: datum.doc_count …

Hi! Thanks so much, it worked! The calculate+flatten allows me to access all the nested values. Now it's just a matter of playing with the fields until I plot something meaningful. Cheers! Inés

How to access double nested data in Kibana/Vega

I'm not sure about the reason of this behavior..
