Aliasing fields in visualizations

Elastic Stack Kibana
2

You can use translate plugin for this data (in logstash).

filter {
  translate {
    dictionary => [ "1", "Net Banking",
                    "2", "Cash On delivery",
                    "3", "Mobile payment" ]
  }
}

Or another way, you can use script field in kibana

 if (doc['payment_status'].value =1) { 
    return "Net Banking";
}
return "";
