Looking to flip plot

Hello I am looking to make this plot accurate. For some reason it is spiraling clockwise when it should be spiraling counter clockwise with the same shape. Any help with this would be great.
It is basically flipped on both the x and y-axis from how it should be.
[x, y] = meshgrid(-2.5:.5:2.5, -2.5:.5:2.5);
xdot = (-1*x) + (2*y);
ydot = (-1*x) + (-3*y);
figure(1)
streamslice(x,y, xdot, ydot, 'black')
grid on
xlabel('X');
ylabel('Y');
title('#2');

Flip the xdot, ydot vectors and their sign
[x, y] = meshgrid(-2.5:.5:2.5, -2.5:.5:2.5);
xdot = (-1*x) + (2*y);
ydot = (-1*x) + (-3*y);
xdot = -fliplr(xdot); % <----
ydot = -flipud(ydot); % <----
figure(1)
streamslice(x,y, xdot, ydot, 'black')
grid on
xlabel('X');
ylabel('Y');
title('#2');
axis tight
