How to convert string field into metric?


I am really new in Grafana and I don’t know how to plot text into a graph. I want to use a field that is showing a number but is a string field. How can I use this field into a graph?

I don’t know if the problem is that I am sending the log in a bad way to elastic.

Thank you,

Please add keyword behind the field, like some.number.intext.keyword

Is that resolved… I need to calculate the values but its still displaying like string … i have used just as .keyword still same issue
