I'm relatively new to Elastic Search and Kibaba, so I'm unsure if this is user error or a bug. The short version is my chart data does not show up with time windows less than three hours - I'm using Elastic Cloud. - I've upgraded to 7.10. - I have a Lens chart whose data will show when I set the time window to the last three hours. - However, if I change the time window to show data in the last two hours, NO data shows up - My timefield is a field named `timestamp` whose type is date and is stored as milliseconds since the epoch Here's my chart with a "Last Three Hours" window set ![Screen Shot 2020-11-15 at 1.09.50 PM](https://us1.discourse-cdn.com/elastic/original/3X/2/3/23ecce54d701ab2cb5143b96ceb5e3e533e10225.png) Data appears to show up for the times 18:30 - 21:00 However, if I change that time window to "Last Two Hours", I see _no_ data, even though this time window (19:15 - 21:00) is within the previous window. ![Screen Shot 2020-11-15 at 1.10.17 PM](https://us1.discourse-cdn.com/elastic/original/3X/e/4/e4e5e92652a38bd87d5fa33a3634ddae4c8e5307.png) Is this a bug, or is there some subtle (or obvious?) nuance to the handling of time/indexes/data/etc that I'm missing? ---

~~I'm still not sure if this is a bug or not, but I think I found the cause for the missing data.~~ I was able to solve this after a quick chat with some of the engineers on the team. The problem was I was trying to graph some times series data where I was collecting _once entry every five minutes_. If I changed my data collection to once a minute, I was able to successfully get chart lines for times more recent than three hours ago. I was told that the problem was with a sparse dataset the buckets are too small which cause gaps in the charts (and those "gaps" in a line chart mean no data) There's a few ways to fix this without collecting data more frequently. The first is to set a minimum interval on the chart. ![Screen Shot 2020-11-18 at 10.12.37 AM](https://us1.discourse-cdn.com/elastic/original/3X/0/9/096baf518cf2be935674568d198e73558806ed2d.png) The second is configure how your chart behaves when there's missing data. Lens can fill those gaps in a way that makes sense for your use case. ![Screen Shot 2020-11-18 at 10.21.55 AM](https://us1.discourse-cdn.com/elastic/original/3X/6/8/68ead11231d9b848465b479a4376e6530f152d50.png) ---
