  1. Hi I am struggling to log (and graph) a number of global variables that have been calculated in sequences. Have got the graphing working but it wont log the data for me. I have logging set up for raw data from inputs and am wanting to log the global variables for a few hours at a time so from what I can see logging may be better suited than export sets. I have created a test channel for each variable I want to log (and graph) as below: I then have a sequence running to make the variable a string in the channel While (1) Graph_DT_Flow.AddValue(insertTime(DT_Flow,systime(),0)) Graph_kW.AddValue(insertTime(kW,systime(),0)) delay(1) endwhile This allows me to graph the channels which is working but when I try to log them the column when opened in excel only has the heading. If you could help with this it would be amazing!!
  2. 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.
