Lockie Posted September 3, 2021 Share Posted September 3, 2021 Hi I am trying to create a graph that begins at zero at a zero time stamp. However when I change the graph x expression (in graph properties) from "time" to anything referencing "systime()" the trace disappears. My approach was to use the start time from a button that runs the below code: global expStartTime1 = systime() // Test Phase Timer global expStopTime1 = 0 global GraphTime = Time() and create a graph using the x expression "systime()-expStartTime1" (with bottom axis set to time and date). I have tried heaps of things but it appears that when systime() is used I lose the data? Any help would be really appreciated. Quote Link to comment Share on other sites More sharing options...
