I am new to elastic and Kibana and encountered a problem with the Date Histograms in Kibana.
I have two indices with multiple date type fields. On one Index I have the field "date" and on the other the fields "lastLogin" and "firstLogin". When I create an Index-Pattern and choose eg. "lastLogin" as Time-Filter, only the Date Histogram for "lastLogin" is correct.
In the case of "firstLogin" the Graph seems to be right and also changes when I change the Time Picker Range, but the Label of the X-Axis does not change and stays the same all the time.
In the other case of "date", I simply get the message that no results were found.
I made sure, that the date format is the same in all three cases. All fields have the format YYYY-mm-ddTHH:mm:ss.
For the import of the data I am using the NEST API for C# and the data originates from a MySQL database.
Does anyone has an idea what I am doing wrong and how to get this fixed?
