Data analysis systems and related methods. An implementation of a method of determining a relationship between a variable of interest and one or more process variables represented by a corresponding plurality of tags may include accessing a data historian including historical data including a variable of interest and a plurality of tags. The method may include defining a plurality of bins, retrieving historical data corresponding with the plurality of bins using the data historian, filtering the historical data for each of the plurality of bins using one or more filters to produce filtered historical data, generating an output display using the filtered historical data for the variable of interest and each of the plurality of tags, and determining which of the plurality of tags correlate with the variable of interest using the output display. The output display may include an overlay CUSUM chart and a correlation plot. |
