Hello
try
in the timepicker => "last 5 years "
disable max value , set avg .

check data format in index pattern .=> screen

3

i still cannot see , i check and set to avg and nothing is showing up

4

What is the type of the field m5 showed on the index patterns " * metrics *"

Is the index pattern * metrics * regrouping differents index ?

5

iimage

the metrics regrouping only indexes of out metrics

6

In your kibana viz , check in "metric and axes" if you set bounds

7

i enable Scale to Data Bounds but i still don't see anything

Do you see something if set only "count" on y axis ?

It means ,it does not find any documents .

In your visualization go to "inspect>view request>response"

Can you check you dataset ?
It seems you have null values in the field m15 .

there was a space in my mapping in each field

i remove the space in each field and it fixed!
