Enumeration of classes in inheritance

Dear all,

I have 2 files with two column vectors each from which I would like to plot each file collumns versus each other. Bellow you can find my code so far:

classdef Data_load
    properties
        Column1 
        Column2
    end
    methods
        function obj = Data_load(Data)
            if nargin > 0
            obj.Column1       = Data(:,1);
            obj.Column2       = Data(:,2);
            end
        end  
        
    end
end


classdef PlotsClass < Data_load
    methods
        function plot_Column1_vs_Column2(obj)
                figure(1)
                plot(obj.Column1,obj.Collumn2);
        end        
    end
end

First_file = PlotsClass(First_file_Data)
First_file.plot_Column1_vs_Column2()

Second_file = PlotsClass(Second_file_Data)
Second_file.plot_Column1_vs_Column2()

Now, I would like to plot the collumns of both files in one plot. How is it possbile to create a subclass that iterates through the data of the objects of the PlotsClass? So far I just use a static method in a seperated class but I would like to know if there is a better way of doing it.

I might neither fully have understood your code nor the title of the question. Nevertheless, I think this is a better approach.

%%
data(2) = Data_load( Second_file_Data );
data(1) = Data_load( First_file_Data );
%%
pc = PlotsClass; 
pc.plot_Column1_vs_Column2( data )

where

classdef    Data_load
    properties
        Column1
        Column2
    end
    methods
        function obj = Data_load(Data)
            if nargin > 0
                obj.Column1 = Data(:,1);
                obj.Column2 = Data(:,2);
            end
        end
    end
end

and

classdef    PlotsClass < handle
    methods
        function plot_Column1_vs_Column2( this, data_obj )
            figure(1)
            hold on
            for jj = 1 : length( data_obj )
                plot( data_obj(jj).Column1, data_obj(jj).Collumn2 );
            end
            hold off
        end        
    end
end
