Records
Records A data record is a group of data fields that are related. A data field is for example an article number, article size, production date etc. In mathematics in particular, we are interested in the data fields that we name in the analysis as a table of values. A value table assigns a natural or real number with a constant difference between the numbers based on the specified rule (function) to the respective pair of values. We have already seen the representation of a function. Now we would like to learn how to represent several functions in one coordinate system. A plotter can manage multiple records. Each data record has its own values for color, drawing style, etc. There are two ways of writing multiple functions in Java. The first option is to call the "nextDataSet ()" method. When this method is called, a new data record is automatically created in Plotter. Subsequent calls to "add ()" are then automatically assigned to this new d
