I'm not sure I understand what you're asking to do, but I think you're asking if you can see the records that are being used to generate a visualization. So that, as you apply filters and narrow things down, you can also see the records in Elasticsearch that match those filters.
If that's right, the answer is mostly no, but it kind of depends what you want to see. If you have a saved search (from Discover) in your dashboard, it'll show the matching records.
However, if you have a visualization (Table, metrics, bar charts, etc), then no. The reason being that those things are created using the aggregate data. You mentioned average, but it could be count, sum, media, percentile, etc. It's a search, using aggregations, so the data coming out of Elasticsearch doesn't include any of the underlying records, but the aggregated results of the search on your data.
Let me know if I misunderstood what you are asking for. I'm not sure what you mean by "dynamic chart."
