    Historical Trending issues on FactoryTalk

    Good morning,i have an issue with the trends at my station, the customer requested to see the current values on the botton display of the trend object, i had it setup to have to data server source be "poll historical data" which doesn't show current values, we changed it to "realtime data server" but we have a jump from the last historical value to the current value, i attach a picture of how it looks, i don't know if it might be a problem with the time configuration on my station, or a datalog model issue,any help will be very appreciated

    Good morning @Alzorrilla,

    I can think of a number of things which can cause that, and to narrow it down can you share:

    1) What version of FT you are using, and is it SE or ME?

    2) How is your Datalog Setup? Screenshots are good if it's easier

    3) Are the pens on your trend added from the Datalog? And is the data source the datalog?

    Thanks,
