I am trying to merge 2 ping graphs. 1 for my firewall and off net (lets say googles DNS). When I create both these graphs individually they are measured in ms, which is fine and what I would expect.
However, What Im seeing is below.

Graph 1 Google DNS averaging about 10ms with a spike in it
Graph 2 fw-core ups and downs arounds the 8 - 9ms.
Graph 3 Them combined. What you will notice is the measurement is now in seconds and the firewall is now up at the 8 - 9 seconds rather than the ms.

Just to be clear and upfront the 2 different devices are using different templates to get these. The fw using UniFi template and the Google DNS using the ICMP Ping template.

Result:
See screenshot...

Expected:
My expectency here would as they both measure in ms that they should both represent in ms.
