Customer has been using an iFix picture with a chart object for years. There are many VBA functions in this picture which manipulate the chart object in a number of advanced ways (e.g. where stored trends from the past are superimposed onto current trends, etc). Right now, the chart object accesses information from iHistorian (using the "Hist." connection). The iHistorian server will be taken out of service and an OSI PI server will be implemented. How can this same chart object be configured to read data from the new OSI PI server? Using an OSI object in the iFix picture is the least desirable option as all functions and scripts would need to be re-written.
