Hello, this is a very similar question to [Quarter date histogram in Kibana 4](https://discuss.elastic.co/t/quarter-date-histogram-in-kibana-4/34644) Basically, when I'm creating a timelion graph with a custom interval=1M, months start on the 15th or the 16th... which is not intuitive. 🙂 Please check the attached screenshot How do I specify the start dates of months? Thank you and best regards, Domenico Raimondi ![image](https://us1.discourse-cdn.com/elastic/original/3X/2/6/26bd3e5502a94d2222fadfc90748e9bc1ec0fd63.png) ---

Do not use `interval` in the `.es` function. the docs for `interval` state " **DO NOT USE THIS**. Its fun for debugging fit functions, but you really should use the interval picker". To set the interval to Months, use the `Interval` select located above the `Timelion Expression` input. ---

Ok, I understand that it should not be used. Is there any other way to specify a similar style (flat line for the whole interval period, instead of just a slanted line connecting the dots), without using .bars() ? BTW Thank you for your quick reply Nathan 🙂 ---

You can set steps to true in the `lines` method to show line as step, e.g., do not interpolate between points. `.es(index=kibana_sample_data_flights,timefield=timestamp).lines(steps=true)` ![07%20AM](https://us1.discourse-cdn.com/elastic/original/3X/0/b/0b1ccb67300b3793c8033214880cd6042ad2a8b3.png) ---
