Hi,
I'm having the same issue. After setting up a date histogram, daily, and getting the ouput I get the titile formatted as "millis:Label".
I have setted up the date format for that field in Kibana Index Pattern configuration as "DD/MM/YYYY" getting at the example output the expected value, but it seems that this configuration isn't enought for Data Table visualization.
Can you provide me one solution please?
Greetings,
Javi.
