I'm tracking down the response times of each API call. I'm pushing the response time as a field into an ES index. I need to create a visualization of each API with the date histogram on X-axis and processing time (not the sum or count) in Y-axis. The goal is to get a graph of processing time over a period of time interval. But the problem is on Y-axis the aggregation shows the metrics like count or sum or average. But I want unique value of the processing time to be shown on Y-axis. ---

Hi @bharath.krishn2 - So to make sure I understand, you aren't wanting to see the average of the response times, rather, you want to see each document's response time value represented individually on the y-axis? In general, visualizations are only going to give you an aggregated view of the data. If you use a date histogram with sufficiently small interval, then in many cases average response time could basically be representing a single document anyway. (Depending on how far apart the timestamps are for each entry). But there isn't a way to visualize each individual document. One hack would be add a sub bucket terms aggregation on something unique, like the `_id`, which would then split each time interval up into a different series per-document. But this is not going to be performant on large data sets, and I suspect it isn't what you are looking for anyway. Does this help answer your question? Thanks Luke ---

Thanks for the reply@lukeelmers . Yes, I don't want the aggregation of a field on the Y-axis. Instead I need the actual value of the field from the document to be charted on the Y-Axis. I tried the hack which you mentioned, but it didn't work out. There are millions of documents on the index and I'm getting memory issue in elastic search. ---
