Graph should display the delta like single stat

Hi, i use a single stat as delta value (SingleStat Plugin -> Options -> Value -> Stat = Delta). When i use a time range “today so far” it shows me correct values (for example: today the endpoint /metrics and /env has each 5 requests, so it shows me 10).
Now i want a graph that shows me the same statistics but splittet. So i want in my graph to lines: one for requests to /metrics and one for /env. Thats no problem. My problem is that the graph shows me the total value of requests and not only the delta of my specific time range :frowning:
