The Diabetes SIP graph is not automatically filtered by the patients with Diabetes.
To review your Diabetes SIP items you need to first filter on Condition = Diabetes.
The filtering is not done automatically as some of the items may be of interest for the wider patient population eg. CHD patients who have not had a BP in the past 6 mths.
Diabetes SIP displays your data as a breakdown of diabetes care items:
