In Ireport Professional 5, I have several charts that are generated by data in a sub dataset. I would like to update chart properties based on the data in the sub data set that is filling the chart or other variables, parameters, fields, etc in that sub data set but I can't. Is there anyway to access varables, parameters, or fields from a sub data set outside of that dataset or even just for the properties of the objects that are connected to the dataset?
