[m,n] = size(y);x1 = X(:,1);x2 = X(:,2);for j=1:1:n for i=1:1:m if y(i,j)==1 scatter(x1(i,j), x2(i,j), 20, y(i,j),'k', '+'); else scatter(x1(i,j), x2(i,j), 10, y(i,j),'y', 'filled'); hold on; end end endlegend("Admitted","Not Admitted");
X is a 300×2 matrix consisting random data and y is a 300×1 matrix consisting only 0 and 1. I want to plot a 2D scatter graph of x1 and x2. Based on the value of y i.e. 0 or 1 the marker of the plot will be changed. But both the legend showing the same marker. I dont want to use any other plotting function , rather want to stick to scatter. The plot is showing like:
