Description:

Ever since we upgraded to Zabbix 3.4.x I really miss the feature that the simlple graphs under latest data don't show the source anymore. The source being history or trends. I always thought myself that this feature was simply deprecated with 3.4.x and accepted it.

But today I read through the 4.0 alpha Documentation and discovered that this might still be a thing:
https://www.zabbix.com/documentation/4.0/manual/config/visualisation/graphs/simple#recent_data_vs_longer_periods

So I switched back to the 3.4 Documentation to find it also mentioned there:
https://www.zabbix.com/documentation/3.4/manual/config/visualisation/graphs/simple

So my report is as following: Is this feature really deprecated, which I don't hope, since it was always a nice and helpful indicator, then the documentation should be updated accordingly. Especially is there a page where it is stated that it got removed??

Or on the other hand: If this isn't deprecated, why is it missing since 3.4.x?

Steps to reproduce:

1. Login to Zabbix Frontend
2. Switch to Monitoring -> Latest Date
3. Open any numerical simple Graph
4. Take a look at the bottom right to look out for any text

Result:

Expected:
