WebIQ Trend does not plot points. Moves vertically as a horizontal line.

[AndreasAA]

I have set up a trend and it is receiving the values. The problem is that the plot is a horizontal line that moves vertically. It seems like it is not storing the previous values. 

Is there a setting I'm missing?

With the provided information it's impossible to answer this.
However, as it looks like you have a text display next to it - does that display change when the value changes? What we have to do here to analyze this:
1. Is the item actually connected correctly and does it change when the source changes?
2. When the source (i.e. OPC-UA server) changes the value can you see that change in UA Expert as well? If not, the OPC-UA server has probably not been setup correctly.

Please provide the log file and the HMI for analysis.
