The dashboard included in the chart currently make uses of delta on counters. For example. https://github.com/kyverno/kyverno/blob/5557d6c85d7e1866ebd3bed5c1c3a4c9d55a3881/charts/kyverno/grafana/dashboard.json#L2816

I believe delta is meant to be used for gauges. In this situation this can cause problem because delta does not take counter resets into account. This means that you can end up with negative values of admission requests, for example:

I believe increase is probably the proper function here since it takes counter resets into account:
