Problem create dashboard

[Lisouu_13 (Baumann)]

Hello, I want to create my first dashboard on kibana 7.13, but I can't do it. I would like to make a graph against the elapsed time that I specified in the data, but the timestamp does not appear anywhere. So i really need help please.

Hi,
it could be because of two missing steps:

• have you mapped correctly your data? do you have a date field?
• have you created an index pattern in Kibana?

PUT /pol
{
  "mappings": {
    "properties": {
      "Date": { "type": "date", "format": "yyyy-MM-dd HH:mm:ss"},
      "Pulse": { "type": "double" },
      "mm": { "type": "double" },
      "Cumul42min": { "type": "double" },
      "Temp": { "type": "double" },
      "Vitessevent_km/h": { "type": "double" },
      "Ane_Temp": { "type": "double" }
      }
    }
  }
}

Yes i have a mapping, this is my index pattern, and i send a screen of my kibana too

I also noticed an issue, I have about 43,000 pieces of data to publish to Elasticsearch, and I notice that only 178 pieces of data are published. I'm posting with requests on Python. Can you tell me how to publish all my data please?
In addition, on my kiabana I cannot preview the data on the left, a warning sign also indicates it to me.

Sorry @Lisouu_13 I can't see your screenshots, can you please repost them?

Can you tell me how to publish all my data please?
What do you mean by publish? where do you see that only 178 documents were indexed? can you report the output of GET /your-index_name/_count

kiabana I cannot preview the data on the left,

Can you share the warning sign content?
