Creating Graphs

To open a new figure with handle 1 type
>> figure(1); clf;
whereas 1 clears the current figure. For this demonstration please load the variables C and X form the file winedata.mat
>> load winedata X C
X is a 2 dimensional matrix, where each column specifies a point in the 2 dimensional plane. The corresponding element of the vector C defines to which class a point belongs. To plot the point sets of all three classes in different styles type
hold on
The command hold on holds the current plot and all axis properties so that subsequent graphing commands add to the existing graph. To label the axis use
xlabel('Markmal 1');
ylabel('Markmal 2');
legend('Klasse 1','Klasse 2','Klasse 3');
puts a legend on the current plot using the specified strings as labels. To see further styles of 2-D and 3-D plots start the Matlab demos
