If I have metric C which is the sum of metric A and metric B. I created metric C with search query "id1:0210" and give the total of 42,187 I created metric A with search query "id1:0200" and give the total of 35,343 How do I produce metric B, which is C - A, in Kibana metric visualization (give total 6844) ? What operator should I use specifically? ![](https://us1.discourse-cdn.com/elastic/original/2X/0/05c852423d703abfa2983fc7d76f3ca889c21ad2.png) ![](https://us1.discourse-cdn.com/elastic/original/2X/7/7cc5b96da8254b7a66758acbc0bd985f7a9626f4.png) ---

You can't do this unfortunately. ---
