I am using Kibana [5.Is](http://5.Is) there a way to set ymax and ymin for time of format HH:mm:ss ---

Hi @Padmavathy, the `ymin` and `ymax` fields are number fields and as such do not accept dates as input. But if the date displayed on the y-axis is stored as a timestamp, you can use unix timestamp values in these fields. A simple way to convert dates to timestamps is using the `date` utility on linux or macos systems, e.g. ``` $ date -d '2008-01-01 09:17:53' '+%s' ``` ---

Normally time is in the X-axis. but generally, you can have automatic y-axis data range bounds or set static min and max bounds for y-axis in option --\> Set Y-Axis Extents and cale Y-Axis to Data Bounds. ![](https://us1.discourse-cdn.com/elastic/original/3X/d/7/d7fe0e584e62cbf9e6d272f956d1e194444a63ef.JPG) ---

Thanks @weltenwort but i have range of dates.When i set extent as epoch time i am not able to visualize the points.can you help with this issue ---

Could you tell me a bit more about the structure of your data? What do you use as the y- and x-axis aggregations, what types and value ranges do the fields have? ---

I am using date in x axis with datehistogram and time in y axis with 24 hour format ranging from 00 to 24 .what I need is to display time lets say from 4am to 6pm.I tried with epoch points are not getting plotted ---

So the field on the y-axis is of the integer (or short/byte) type? What aggregation are you using on the y-axis? ---

No its not of integer type.Its of type date and i have given min as aggregation.I am displaying time in format HH:mm:ss which i configured in the index pattern settings ---

In that case specifying the lower and upper bounds as timestamps in the `y-min`and `y-max` fields should work. Just make sure to specify them in milliseconds, since this is the timestamp precision Elasticsearch uses at the moment. ![](https://us1.discourse-cdn.com/elastic/original/3X/1/5/15d2cb27d5653b97ca54f810d6e5cffca4a0e41c.png) Formatted date strings can not be used in these fields, I'm afraid. ---

Thank you @weltenwort when i set yaxis to data bounds i get the whole graph but i am not able to set a specific time frame I have tried using milliseconds in set yaxis extents but i get a straight line.The time frame is adjusted say i set from 5 am to 8 pm it gets filtered out but i get a straight line instead of a line graph ![](https://us1.discourse-cdn.com/elastic/original/3X/e/0/e0f6eedea0cf7dfe63fd3e16a96a591be1484656.png) i need a line graph with multiple points and within a specified time frame.Is this possible? ---

It looks like all values are below your `y-min` threshold. Have you accounted for the fact that the timestamp is usually in the UTC time zone? ---

Even if the value is above my y-min threshold i still get a straight line and i have set the timestamp to browser settings in Advanced Settings tab ---

When treating the timestamp values as numbers (which is what we do here) they are not timezone-adjusted. ---
