Hi,

I recently upgraded to the brand new **ELK version 7.5** , everything is working great except one annoying issue at the Discover's Pane:

I have an Index which contains 2 years worth of data, each document is timestamped (using the Date field), but documents before a specific date have missing/null values in one of the fields (which is not the Date field).

Whenever i set the Date's range to show data with documents that have null-value in the specific field, the Date histogram (at the top of the Discover's Pane) suddenly disappears.

In other words, the Date histogram is showing only when i filter the index to show only documents with existing value at the specific field.

I couldn't find any setting to solve this in the documentation.  
Before the upgrade i was using **ELK version 6.5** and i had no problem of this kind.

Thanks.

Hey @tomervain, I'm having trouble replicating what you're seeing. Do you have any "filters" specified for Discover?

 ![Screen Shot 2019-12-16 at 8.40.31 AM](https://us1.discourse-cdn.com/elastic/original/3X/5/c/5c65353343d2df39d8a97cf88058d632cff4bd08.png)

Also, if you wouldn't mind clicking the "Inspect" header button, selecting the "Request" tab, and then copying the query and posting it here, it'll help us diagnose further:

I believe this is [https://github.com/elastic/kibana/issues/52152](https://github.com/elastic/kibana/issues/52152) which will be fixed starting in 7.5.1
