Class Overview




Data set used to represent a data collection to plot in a chart




Author(s):


    
        





    







Methods
















Child classes:






Image_Graph_Dataset_Function

	
Function data set, points are generated by calling an external function.






Image_Graph_Dataset_Trivial

	
Trivial data set, simply add points (x, y) 1 by 1






Image_Graph_Dataset_VectorFunction

	
Vector Function data set, points are generated by calling 2 external functions, x = sin(t) and y = cos(t)
