Good Day, I want to display, for each alarm operator, in a graph the following:

1. Total alarm signals received per operator with each one's average acknowledge time.For example:

Operator A: 210 signals received. Average acknowledge time: 00:00:48 seconds.
Operator B: 450 signals received. Average acknowledge time: 00:03:20 seconds.

Thus I want to create three graphs:

1. Signal to acknowledge.
2. Signal to Dispatch.
3. Signal to Completion.

Many thanks in advance.
