The KPIs used as seen on the screenshot are
Average Daily Time
Average Call handling Time

The colors are soft and the period parameter is at the bottom which is not a really user friendly. Parameters by default should be either on the top of the dashboard-page or on the left hand side or just near the vicinity of the dashboard object (chart or table).
