Ok, so I have a mqtt broker publishing to vt scada, and vt scada doesnt like it for some reason. It gives me a flat line for a graph every time the value updates in historical data viewer. It also seems to update values from all time to the most recent value given. For exampe, i have a current value with max min and average set at 26. Then mqtt publishes to vt scada the value of 25. All values that ever existed get magically transformed into the most recent value of 25. This results in a line flatter than the fields of Iowa and a new min max and average of 25. I would not put this issue past user error, and I have provided a photo that is hopefully useful 
If you are confused at all I will gladly send more pictures or whatever you need.
-Thanks
