Hello all, I hope that I don't make a mistake and that the topic is not opened somewhere. I want to use dates in Y-axis, and add the start time (in HH:mm:ss format) and the end time (same format) to show the tendency of batch in this axis. These fields are in date format, not number. On the X-axis, it's just a date histogram by day. I don't know what kind of aggregation I need to use (Max and Min are the only choices that allow me to show time, but it's completely wrong. Could you help me ? Regards, Charlotte ---

Could you provide a sample of your documents as well as some sort of sketch or screenshot of what you're trying to accomplish? ---

I have this kind of data in my discover part : ![Discover_Y-axis dates](https://us1.discourse-cdn.com/elastic/original/3X/0/5/05618d31a006cf443d9dd26f2d206659e62c2942.PNG) I want to use the EndTimeBatch and the StartTimeBatch in my Y-axis, and in the X-axis, the standard date histogram by day. At final, the graph looks like that : ![Discover_Y-axis dates Batch Endtime and start time](https://us1.discourse-cdn.com/elastic/original/3X/0/f/0f8557f56cd2c396a17780028d8953971da33706.PNG) But I don't find how to use date in the Y-axis. I hope my answer is more clear. Regards, Charlotte ---

What type do you have mapped for StartTimeBatch and EndTimeBatch? ---

Hello I have the exact same need. I want to check the tendencies of our nightly batches. I guess I could transform the time part of my @timestamps into a number of seconds since midnight but it won't be really readable. any idea ? thank you. ---

The type of StartTimeBatch and EndTimeBatch is "date". I thought to transform in seconds, into a number format, but the legend of the Y-axis is not easily readable (you have seconds, not HH:mm:ss). Maybe it's possible to transform on this format with the JSON Input in the advances option. Regards, Charlotte ---
