Groov 3.4 allows operators to trend more data over a longer period—up to five years. The mobile operator interface system’s built-in trend gadget offers an interactive type of trend that handles more data points. Operators can choose between classic and interactive trend types. Classic is the original trend for a relatively small number of data points, collected over a period of up to seven days. Interactive is the trend for more data over longer periods. In both Classic and Interactive trends, operators can download individual pen data for the entire trend period to log it.
