Hello I want to use 'x' or 'o' in the plot regarding the value of each elemants in T.
so if point (1,3) is labeled with 0, I'll put 'o'
if point (1,3) is labeled with 1, I'll put 'x'
if point (1,3) is labeled with 2, I'll put 'r'
How can that be possible?
clc;clear;
data = load('test_data.txt');
sample_size = size(data,1);
X=[ones(sample_size,1) data(:,1) data(:,2)]'; %Each coloumn is a sample
T = data(:,3)'; % Labels for each sample
plot(X(2,:),X(3,:),'x', 'MarkerFaceColor', [0.2, 0.2, 0.5], 'MarkerEdgeColor', 'k', 'MarkerSize', 7)
title('Plot of test data')
grid on;
xlabel('x1');
ylabel('x2');

That's how I workarounded...
figure
scatter(X(2,:),X(3,:),sample_size,T, 'filled')
% Add title and axis labels
title('Plot of training data')
xlabel('x1')
ylabel('x2')
