Create grafana Dashboard from elasticsearch Souce failed

Hi,

I am start using grafana last week and i’m using elasticsearch for data source. Connexion is ok and i can see all my key data in my json structure. Now i can display any chart. I start with a basic count like the number of documents save in real time and my chart look like this

Count anytime is egal to 0. I don’t understand why. I try to combine multiple parameter and it changes anything.
Can you help me please?

Thanks

How can i see the query grafana sent to elasticsearch?
For some queries i get an error but i can’t find where i can see log or query that sent to elastic.

You can troubleshoot queries by checking the raw query and raw response data in the Chrome Dev Tools Network tab. See this guide for more details.
