Real number of errors for logback_events_total

on one Grafana screen we have this panel that shows number of error/warning of a Spring boot application. In the last 6 hours we have 8 errors and value on panel is 0.980, metric is

sum(increase(logback_events_total{app=“retail-program-service”, instance=~"$instance.*", level=~“error|warning”}[1h]))

How could I have real number 8 instead of 0.980?
