Hello Swen,
I began looking into your issue and believe I understand the problem correctly, but I want to verify to be sure. It sounds like when you plot the data based off the system time, it loops back and overwrites the data every 24 hours. What you would like to happen is have a continuous stream of data displayed for 60 hours. Using the system time alone can not accomplish because it only contains the time, and not the date. For instance, the application has no way of knowing the difference between 3/3/08 12:00 -vs- 3/4/08 12:00.
So, one workaround would be to go into the actual graph properties. If you right click the graph and go to properties then the format tab, there are several built-in format styles. Please try changing the format to Date and then the bottom option in the Format String "mm/dd/yy hh:nn:ss".
Best regards,
Benjamin
