divide row and plot it

I have this data,

data=[1 2 3 1 2 3; 7 8 9 10 11 12]

, the data consist of 2 columns, So i want to take a for loop for i = 1:3:end , and then plot it. So after the loop, the result will be,

1 7 and 1 10

2 8 2 11

3 9 3 12

The curve will be

Please I want it by Loop or if, not manually.

data=[1 2 3 1 2 3; 7 8 9 10 11 12] ;
data = reshape(data,2,3,[]) ;
figure
hold on
for i = 1:2
    plot(data(1,:,i),data(2,:,i))
end

Try this:

data=[1 2 3 1 2 3; 7 8 9 10 11 12]

data = 2×6

1 2 3 1 2 3 7 8 9 10 11 12

[rows, columns] = size(data);
for col = 1 : 3
    data1(col, 1) = data(1, col);
    data1(col, 2) = data(2, col);
end
data1 % Show in command window.

data1 = 3×2

1 7 2 8 3 9

for col = 4 : columns
    data2(col - 3, 1) = data(1, col);
    data2(col - 3, 2) = data(2, col);
end
data2 % Show in command window.

data2 = 3×2

1 10 2 11 3 12

% Plot them
plot(data1(:, 1), data1(:, 2), 'b-', 'LineWidth', 2)
hold on;
plot(data2(:, 1), data2(:, 2), 'r-', 'LineWidth', 2)

Is that what you want?
