Another idea is that the Group definition may have a problem. This is in the mcsTemperature.ini. I did a simple test with 2 virtual devices and let data collect for awhile. I defined a group with these two. The following is what is in the group section for this test chart. The resultant chart is attached.
Code:
[Group] Default="None","LinTab" Dtest="None","LinTab","_47"-1,"_48"-1
