Hello, I am quite new in TimeLion and I have a very basic problem. I have data by month, and more precisely, each document (or row) has as date the first day of the month. The display of the line is ok. But, when I use the time cursor, there is like a shift between the y-axis and the time-cursor : when the time cursor is in the position of the 2nd of January, the time cursor displays the value of February. I know Timelion use 'buckets' (even if I don't really know what it is). Is there any configuration, or function to specify to Timelion that the date should be the beginning of the bucket, instead of the end ? Thanks in advance, and thanks for so cool functions in TimeLion !!! ---

hi @mamachin, Are you referring to the vertical line showing the wrong date? Perhaps you could you attach a screenshot or gif of what you are seeing? thx, ---

Yes I’m referring to the vertical red line. My data is 2017-01-01 0.0 2017-02-01 3168.99 In the printscreen, the time cursor corresponds to 3rd January (let’s say), whereas the value displayed is the value of February. I would like to displayed the value of January. And my expression is quite simple .es(index=myindex, timefield='date', metric='sum:data’) [cid:image001.jpg@01D285E2.0EE816C0] A piece of data is usually not relevant to an instant (a point in time) but to a period (a segment of time). It seems to me that Timelion should (or maybe do it and I don’t know) offer to declare that the relevancy period - ``` ends (that’s the default behavior) at the mentioned date, or ``` - ``` begins (that’s what I need) at the mentioned date, or ``` - ``` the mentioned date is the middle of the relevancy period ``` ![](https://us1.discourse-cdn.com/elastic/original/2X/d/d691d62dc5db3e2af14df22651a11de747cbb5bb.jpg) ---

@mamachin, thanks for the added explanation. I understand now. I don't believe there is a way to modify the book-ending behavior of timelion, or the ability to indicate a duration on a date-stamp. I'd agree with you that the label is not an intuitive read-out value. I would log this as an issue in [https://github.com/elastic/kibana/issues/new](https://github.com/elastic/kibana/issues/new), thx. ---
